Elle is buying new flooring for her kitchen

const2013 [10]

Answer:

The total area of the two rooms is 188.25 square feet

Step-by-step explanation:

Given:

Area of the kitchen = 132 square feet.

Dimension of the Laundry room = 8 1/3 feet by 6 3/4 feet.

To Find:

The total area of the two rooms = ?

Solution:

Area of the two rooms = Area of the kitchen + Area of the laundry room

Area of the two rooms = 132 + Area of the laundry room

Area of the laundry room = $(8 \frac{1}{3}) \times (6 \frac{3}{4})$

Area of the laundry room = $\frac{25}{3} \times \frac{27}{4}$

Area of the laundry = $\frac{675}{12}$

Area of the two rooms = $132 + \frac{675}{12}$

Area of the two rooms = 132 + 56.25

Area of the two rooms = 188.25 square feet
