Question

Can someone help me on number 21? PLEASE

Answer 1

10.68 meters

Explanation:

The first step is to subtract the sum of the other 3 sides.

45.56 - 24.2 = 21.36

21.36 is equal to two equal sides. This means you can divide 21.36 to find the length of one of those sides.

21.36 / 2 = 10.68
