Question

Use the rewritten formula to find the width of a rectangle with an area of 42 square inches and a length of 16.8 inches.

Answer 1

Length * Width = Area

Width = Area / Length

W = 42 / 16.8

W = 2.5 inches

Answer 2

The width of the rectangle is, 2.5 inches

Explanation:

Given: The length of a rectangle is 16.8 inches , with an area of 42 square inches.

Since Area is 2- dimensional, it has length and width.

Area of Rectangle in square unit is given by multiplying the length by width.

The formula is given by:

Area of rectangle(A) =
`length( l) * width(w)` ......[1]

Substitute the value of Area (A) = 42 square inches and length
`(l)` = 16.8 inches in equation [1], to solve for width(w).

`42 = 16.8 * w`

or

`w = (42)/(16.8) = 2.5` inches.

Therefore, the width of rectangle is, 2.5 inches.
