Answer:
the length is 40 inches
the width is 14 inches
Explanation:
We start by representation with variables
let l be the length and w the width
Length l is 2 inches less than 3 times width (3w)
l = 3w-2 ••••(i)
Mathematically,
we have the perimeter calculated as follows;
P = 2(l + w)
2(l + w) = 108
l + w = 108/2
l + w = 54 ••••••(ii)
Substitute equation i into ii
3w-2 + w = 54
4w = 54 + 2
4w = 56
w = 56/4
w = 14
Recall;
l + w = 54
14 + l = 54
l = 54-14
l = 40 inches
