Answer: 50cm squared
Explanation:
First we need to find the side lengths,
In order to find the area you do,
A = Length x height
we know that the area is 144 and the length is 16.
144=16 x height
144 = 16 x ?
So know we need to find the height, so we do 144/16= 9
so the height 9 cm.
The question is not asking for the height, but the peremeter.
Peremeter = (Length x 2) + (height x 2)
peremeter= 16 x 2 + 9 x 2
peremeter = 32+18
peremeter = 50 cm squared
so the peremeter is 50 cm squared.
hope this helps,
have a great day,
