Goal: Identify the equation that solves for area.
Read each word problem carefully. Choose the equation that you would use to find the area. Click on the correct answer choice.
Which equation can be used to solve for the area?
Sam purchased a picture frame. The length was 9 in., and the width was 10 in. What is the area?
To find the area, multiply the length by the width, or \({\Large\text{A} = l \times w}\)
To find the area, multiply the length by the width, or \({\Large\text{A} = l \times w}\)
Correct! 9 in. \({\times}\) 10 in. \({=}\) 90 sq. in is the equation used to solve for the area.
Lauren is putting new carpeting in her bedroom. Her room is a square with a side length of 10 ft. What is the area of her room?
Because the room is a square, all four sides are equal in length, 10 ft. To find the area, multiply the length by the width, or \({\Large\text{A} = l \times w}\).
Because the room is a square, all four sides are equal in length, 10 ft. To find the area, multiply the length by the width, or \({\Large\text{A} = l \times w}\).
Correct! 10 ft. \({\times}\) 10 ft. \({=}\) 100 sq. ft.
Saul has a pool in his backyard. It is 4 m wide and 6 m long. What is the area of the pool cover he needs?
Correct! 6 m \({\times}\) 4 m \({=}\) 24 sq. m
To find the area, multiply the length by the width, or A = l x w. Remember, area is measured in square units. You are calculating the number of square units that will cover the pool.
