Step-by-step explanation:
let width = w
if width = w, then length = w + 4
Therefore the perimeter is 2w + 2(w+4)
2w + 2(w+4) = 4w + 8
perimeter = 60cm
4w + 8 = 60
<em>-8</em>
4w = 52
<em>divide each side by 4</em>
w = 13
length = w+4
therefore, length = 17
Answer:
uh
Step-by-step explanation:
45 - 15 - 15 = 45 - 30
45 - 30 = (15)
It should be 2 but i’m not positive
