Question

the area of the retangler piece of foil is 11 1/4 square inches its length is 4 1/2 inches what is the width of the foil?

Answer 1

Answer:

The width of the foil = w = 2.5 inches

Step-by-step explanation:

We know that the Area of a rectangular piece:

$A=wl$

Here:

• 'w' is the width

• 'l' is the length

Given that area of the rectangular piece of foil:

Area = A = 11 1/4 square inches

               = 45/4 square inches

               = 11.25 square inches  

                                                                         

Length = l = 4 1/2 inches

                 = 9/2 inches

                 = 4.5 inches

Using the Area formula

$A=wl$

$w\:=\:\frac{A}{l}$

    $=\frac{11.25}{4.5}$

    $= 2.5$ inches

Thus, the width of the foil = w = 2.5 inches
