Given:

Perimeter of the triangle = 99 ft

Length of two sides are 20 ft and 42 ft.

To find:

The length of missing side.

Solution:

Let the missing side be x.

Perimeter of a triangle is the sum of all sides of that triangle.

x+20+42=99

x+62=99

Subtract 62 from both sides.

x=99-62

x=37

Therefore, the missing side of the triangle is 37 ft.
