She needs to find the perimeter of the wall.

The perimeter is 50 ft

Step-by-step explanation:

The wall measures 10 ft x 15 ft, that is,

Two opposite boundaries have dimensions measured to be 10 ft each, and the two other opposite boundaries are measured to be 15 ft each

The wall is rectangular (deciding from these measurements).

Perimeter of a rectangle is 2a + 2b, where

a is the dimensions of two opposite walls, and,

b the dimensions of the other opposite walls. We put

a = 10 ft

b = 15 ft

Perimeter = (2x10) + (2x15)

= 20 + 30 = 50 ft
