Question

The perimeter of this rectangle is 24cm. If the length is 8 cm, what is the height?

Answer 1

h = 4 cm

Explanation:

`2(l + h) = 24 \\ l + h = (24)/(2) \\ l + h = 12 \\ 8 + h = 12 \\ ..(plug \: l = 8) \\ h = 12 - 8 \\ h = 4 \: cm \\`

Answer 2

4

Explanation:

P = s+s+s+s

length = 8

8x2=16

24-16=8

8 / 2 = 4
