Question

A rectangular painting on a wall at Dolores Huerta School has an area of 69 square feet. The painting is 3 feet wide.

Answer 1

Answer:

Length = 23 feet

Step-by-step explanation:

Formula to get the area of a Rectangle

Area = Length x width ( Length x breadth)

if Area = 69 feet and Width = 3 feet Length = x

Area = Length x Width

substitute the values

69 square feet = X feet x 3 feet

69 = 3x

69/3 = 3x/3

23 = X

Length = 23 feet

Proof: 23 X 3 = 69 ✓
