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

Ugo [173]

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.

Each room has an area of ...

A = LW = (13 ft)(10 ft) = 130 ft²

<h3>carpet order</h3>

The order for carpet must be for 2 times the area of one room:

carpet order = 2 × 130 ft² = 260 ft²

Jerry should order 260 square feet of carpet.
