Question

The formula for the area of a rectangle is A = l ∙ w, where A = area, l = length and w = width.A rectangle with a length of 4 millimeters has an area of 44 square millimeters. The width of the rectangle is__millimeters.

Answer 1

Given:

Formula for the area of rectangle is:

$A=l\times w$

Given measurements are:

A=44 square millimeters

l=4 millimeters

The objective is to find: width of rectangle

$\begin{gathered} A=l\times w \\ w=\frac{A}{l} \end{gathered}$

Substituting the values, we get;

$\begin{gathered} w=\frac{44}{4} \\ =11\text{ millimeters} \end{gathered}$

Hence, the width of the recatngle is 11 millimeters.
