Question

LIn lines the bottom of her first pan with aluminum foil. The area of the rectangle piece of foil is 11 1/4 square inches. Its length is 4 1/2 inches what is the width of the foli.

Answer 1

2.5

Explanation:

Answer 2

Width of foil is
`2(1)/(2)` inches

Solution:

Given that area of the rectangle piece of foil is
`11(1)/(4)` square inches

Its length is
`4(1)/(2)` inches

To find: width of foil

The area of rectangle is given as:

To find the area of a rectangle, we multiply the length by the width

`\text{ area of rectangle}= length * width`

Substituting the given values in above formula,

`11(1)/(4) = 4(1)/(2) * width`

Let us solve above expression to find width

`(4 * 11 + 1)/(4) = (2 * 4 + 1)/(2) * width\\\\(45)/(4) = (9)/(2) * width\\\\width = (45)/(4) * (2)/(9)\\\\width = (5)/(2) = 2(1)/(2)`

Therefore width of foil is
`2(1)/(2)` inches
