Bruno is sewing a large rectangular tablecloth for a restaurant. He has 30 square feet of fabric, and the length of the table cloth needs to be 7.5 feet. What is the width of the tablecloth if he uses all of the fabric?

Respuesta :

The tablecloth would have to be 4 feet wide to use all of the fabric. 30=7.5x is the equation to solve this problem. You need to use reverse operations, so 30/7.5=4.

Answer:

The width of the tablecloth is [tex]4\ ft[/tex]

Step-by-step explanation:

we know that

The area of a rectangle is equal to

[tex]A=LW[/tex]

In this problem we have

[tex]A=30\ ft^{2}[/tex]

[tex]L=7.5\ ft[/tex]

substitute the values and solve for W

[tex]30=7.5W[/tex]

Divide by [tex]7.5[/tex] both sides

[tex]W=30/7.5=4\ ft[/tex]
