Area of a rectangle

A rectangle is a 2-dimensional shape have 4 sides

The area of a rectangle is expressed as:

A = lw

where:

• l is the length of the rectangle
• w is the width of the rectangle

In order to get the required width, you will;

Substitute the given parameters

$257 \frac{1}{4} = 10 \frac{1}{2} w\\ \frac{1779}{4} =\frac{21}{2} w\\ w = \frac{1779}{4} \times \frac{2}{21}\\ w = 42.36 in$

Hence the width of the rectangle is 42.36 in
