Problem: the perimeter is 36m, the length is 2m more than three times the width
I need to find the width and length?
l = 3w + 2
p = 2l + 2w
36 = 2(3w + 2) + 2w
36 = 6w + 4 + 2w
36 = 8w + 4
36 - 4 = 8w + 4 - 4
32 = 8w
32/8 = 8w/8
4 = w
l = 3w + 2
l = 3(4) + 2
l = 12 + 2
l = 14
p = 2l + 2w
36 = 2(14) + 2(4)
36 = 28 + 8
36 = 36
width = 4m, length = 14m
