Answer:
Explanation:
L = length W = width
Length is 1.2 times width ⇒ L = 1.2 x W = 1.2W
Perimeter = 2 x W + 2 x L
= 2W + 2L = 25
Substitute L = 1.2W into the equation for the perimeter and solve for W
2W + 2L = 25
2W + 2(1.2W) = 25
4.4W = 25
W = 25 ÷ 4.4 = 125/22
Now substitute found value of W into L = 1.2W to find L:
L = 75/11
