Answer:

192 square feet is the total area of both rooms.

Step-by-step explanation:

Key skills needed here: Rectangle Area, Operations

1) She has 2 identical rooms and each one measures 8 ft. x 12 ft.

2) Most rooms are rectangles, so this one is one too.

3) The area of a rectangle is L x W, with L being the length and W being the width (check my image to learn more)

4) Now you can use the formula to find the area of one room and the multiply it by 2 since there are 2 rooms.

---->> A = L X W = 8 x 12 = 96

Each room is 96 square feet.

96 X 2 = 192

This means the total area is 192 square feet.

Oxana [17]

Answer:

12 servings

Step-by-step explanation:

Given:

Evil bunny's carrot soup calls for 5/8 cups of chopped carrots per serving.

If evil bunny has chopped 7 1/2 cups of chopped carrots.

Question asked:

How many servings of carrot soup can he make?

Solution:

By unitary method:

$\frac{5}{8}$ cups of chopped carrots used for = 1 serving of carrot soup

1 cup of chopped carrots used for = $\frac{1}{\frac{5}{8} }$ = $1\div\frac{5}{8} =1\times\frac{8}{5} =\frac{8}{5}$ servings

$7\frac{1}{2}$ cups of chopped carrots used for = $7\frac{1}{2} \times\frac{8}{5} =\frac{7\times2+1}{2} \times\frac{8}{5} =\frac{15}{2} \times\frac{8}{5}=\frac{120}{10} =12$

Thus, 12 servings of carrot soup could be made.
