Question

Two adjacent rooms are rectangles, both of length 13 feet by 10 feet. Jerry wants to change the carpets in both rooms. How many square feet should he order?

Answer 1

Answer:

  260 square feet

Step-by-step explanation:

The area of a rectangle is given by the formula ...

  A = LW

The area of two same-size rectangular rooms will be double the area of one of them.

__

room area

Each room has an area of ...

  A = LW = (13 ft)(10 ft) = 130 ft²

Jerry should order 260 square feet of carpet.
