Question

What is the width of a rectangle if the area is 7 and 7/8and the length is 1 and 3/4?

Answer 1

4.5

Explanation:

First, think back to literal equations in Algebra 1 or 2.

The formula for the area of a rectangle is:

`a=lw`

Fill in the variables that we know and solve.

`7(7)/(8) =(1(3)/(4))w`

Divide everything by (1 and 3/4)

`((63)/(8))/((7)/(4))=w`

Simplify:

`w=(9)/(2)=4.5`

w=4.5

Answer 2

4.5

Explanation:

To find the width of the rectangle, you must divide the area by the length.

7 and 7/8 divided by 1 and 3/4 = 4 1/2

The width of the rectangle is 4 1/2 or 4.5

check:

4 1/2 x 1 3/4 = 7 7/8
