The length of a rectangle is 3 times the width if the perimeter is 32 square iches whats the area?
1 answer:
Set up variables:
l = length
w = width
p = perimeter
A = area
Relations:
A = lw
32 = 2l + 2w (perimeter)
l = 3w
Find the missing info:
32 = 2(3w) + 2w (solve for w)
32 = 6w + 2w = 8w
w = 32/8 = 4
If width equals to 4, then length would be 4 * 3, 12.
Area = 12 * 4 = 48

Answer:
25
Step-by-step explanation:
5 > x/5
5 × 5 > (x/5) × 5
25 > x
x-2=7
apply additon property of equality
x-2+2=7+2
x=9
I think it would be 363.21 because you are moving the digits down by 10
57.8 ≈ 60
81 ≈ 80
57.8/ 81
≈ 60/80
≈ 3/4
≈ 0.75
The quotient 57.8/ 81 is approximately equal to 0.75~
