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

Explanation:

I think it would be 5

Answer 2

The width of the foil = w = 2.5 inches

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\:=\:(A)/(l)`

`=(11.25)/(4.5)`

`= 2.5` inches

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