Question

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

Answer 1

Answer:

h = 4 cm

Step-by-step explanation:

$2(l + h) = 24 \\ l + h = \frac{24}{2} \\ l + h = 12 \\ 8 + h = 12 \\ ..(plug \: l = 8) \\ h = 12 - 8 \\ h = 4 \: cm$

Answer 2

Answer:

4

Step-by-step explanation:

P = s+s+s+s

length = 8

8x2=16

24-16=8

8 / 2 = 4
