Mrs. Alberts built a pen for her dogs. The pen was 12.5 feet by 7 feet and had a concrete floor. If the concrete floor costs $12 per square foot, how much did Mrs. Alberts spend on the floor?

Mrs. Alberts spent $1,050 on the floor.

Step-by-step explanation: First lets find the area to get the total amount of square feet by multiply length by width.

12.5 x 7 = 87.5 square ft.

We know that it costs $12 per square foot, and we have 87.5 square feet.

So, multiply 12 by 87.5 to find the cost that Mrs, Alberts will spend on the floor.

12 x 87.5 = 1050, or $1,050 for the total area of the floor.

answer: the area of the parallelogram below is 42 square meters.
