PERIMETER FORMULA OF 63CM
1. PERIMETER FORMULA OF 63CM
Answer:
the perimeter is 396 cm.
Step-by-step explanation:
2. The area of a rectangular frame is 63cm² . If the length is 2cm longer than the width, what are the dimensions of the frame?
[tex]area = lw \\63 = ( x + 2)x \\ 63= x { }^{2} + 2x \\ \\ 0= {x}^{2} + 2x - 63 \\ = (x - 7)(x + 9)[/tex]
.
[tex]x - 7 = 0 \\ x= + 7[/tex]
.
[tex]x + 9) = 0 \\ x= - 9[/tex]width=7
length=9 negative number is not allowed
3. find the surface area of the rectangular prismL:63cmH:28cmW:40 cm
Answer:
L x W x H = V = __70,560___Step-by-step explanation:
L= 63 cmW= 40 cm H =28 cmV=70,560 cm✔️That's the Correct Answer!✔️Answer:
Answer is A = 10808 cm
Step-by-step explanation:
Formula: A = 2(wl+hl+hw)
A = 2 × (40 × 63 + 28 × 63 + 28 × 40)A = 10808 cm4. a rectangle has a perimeter of 32cm and has an area of 63cm². what is the length and width?
Given:
P=32 cm
A=63 cm^2
P=2L+2W <---- equation 1
A=LW<------ equation 2
from equation 2
A=LW
L=A/W <--- equation 3
substitute 3 in 1
P=2L+2W
P=2(A/W)+2W (multiply both sides by W)
WP=2A+2W^2 but P is = 32 and A= 63
W(32)=2(63)+2W^2
2W^2-32W+126=0 solve for W
W1=9 W2=7
substitute the value of W to get L
A=L1W1 A=L2W2
63=L(9) or 63=L2(7)
L1=7 L2=9
L=7cm,W=9cm
or
L=9cm.W=7cm

7. the ratio of side of an isosceles triangle triangle is 2:2:3 if the perimeter is 63cm find each leg base
Answer:
18:18:36
18cm, 18cm, 36cm
Step-by-step explanation:
I don't know what is the leg base but the ratio is 18:18:36.
2:2:3 = 2x+2x+3x = 63
7x = 63
x = 9
2x = 18 cm
2x = 18 cm
3x = 36 cm

9. A rectangle has a perimeter of 32cm and an area of 63cm square. find the length and the width
Perimeter of rectangle = 2(L + W) = 32
L + W = 16
L must be = 9 and W must be = 7 / area = 9*7 = 63 cm²
the length = 9 cm and the width = 7 cm

12. a rectangle has a perimeter of 32 cm and an area of 63cm^2. Find its dimensions.
Perimeter: 2L + 2W = 32
Simplify this equation by dividing everything by 2: L+W = 16
Area: LW = 63
Solve the area equation for one of the variables: L = 63/W
Substitute this into the perimeter equation:
63/W +W =16
W is in the denominator so we want to multiply everything by W:
63 + W^2 = 16W
Rearrange into standard form, then solve by factoring or by using the quadratic formula:
W^2 - 16W + 63 = 0
(W-9)(W-7) = 0
W = 7 or 9
Since we generally think of length as being the longer side, we will use 7 for W, which makes L = 9.
This makes the dimensions 7 x 9

14. Find the volume of each cube Length Width Height V9dm-12dm-6dm-63cm-15cm-
a) Cube with a length of 9 dm:
Volume = length x width x height
= 9 dm x 9 dm x 9 dm
= 729 dm³
b) Cube with a length of 12 dm:
Volume = length x width x height
= 12 dm x 12 dm x 12 dm
= 1728 dm³
c) Cube with a length of 6 dm:
Volume = length x width x height
= 6 dm x 6 dm x 6 dm
= 216 dm³
d) Cube with a length of 63 cm:
Volume = length x width x height
= 63 cm x 63 cm x 63 cm
= 250047 cm³
e) Cube with a length of 15 cm:
Volume = length x width x height
= 15 cm x 15 cm x 15 cm

16. Three pieces of timber have a length each of 63cm, 84cm, and 105 cm respectively. A sawmill operator needs to cut the timber into logs of equal length. What is the greatest possible length of the logs?
63cm. Just find their average
17. a piece of wood is cut into two pieces in the ratio of 3:7. If the longer piece is 63cm, what is the length of the wood before it is cut?
The wood was 90 cm long before it was cut.
Step-by-step explanation:
3 : 7
7 represents the longer piece. Therefore,
[tex]63 \div 7 = 9 \ \ \\ \\ 9 \times 3 = 27 \\ { \: length \: of \: the \: shorter \: piece} \\ \\ 63 + 27 = 90 \: cm[/tex]
