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

Answer:

The width of the rectangle is, 2.5 inches

Step-by-step 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) = $length( l) \times width(w)$      ......[1]

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

$42 = 16.8 \times w$

or

$w = \frac{42}{16.8} = 2.5$ inches.

Therefore, the width of rectangle is, 2.5 inches.

Answer 2

Length * Width = Area

Width = Area / Length

W = 42 / 16.8

W = 2.5 inches
