Answer:
Length = 58, width = 10
Step-by-step explanation:
Given:
Perimeter = 136 cm
Length = 5 * width + 8
Find dimensions of rectangle
Solution:
Write two equations
L = length, W = width
2(L+W) = 136 ……(1)
L = 5W+8 …………(2)
substitute (2) in (1)
2(5W+8 + W) = 136
6W+8 = 136/2 = 68
6W = 68-8 = 60
W = 60/6 = 10
L = 5W+8 = 5(10)+8 = 58
