Answer:
length = 10 m , width = 6 m
Explanation:
the perimeter (P) of a rectangle is calculated as
P = 2(length + width)
let l represent the length, then the width w is l - 4
given P = 32 , then
2(l + l - 4) = 32
2(2l - 4) = 32 ( divide both sides by 2 )
2l - 4 = 16 ( add 4 to both sides )
2l = 20 ( divide both sides by 2 )
l = 10
and w = l - 4 = 10 - 4 = 6
length = 10 m and width = 6 m
