Question

The diagonal of a rectangle is 10 units. The width is 6 units, What is the area of the rectangle in square

units?

Answer 1

48 square units

Explanation:

Let the length of the rectangle be x units.

By Pythagoras theorem:

`x = \sqrt{ {10}^(2) - {6}^(2) } \\ x = √( 100 - 36 ) \\ x = √(64) \\ x = 8 \: units \\`

Length of rectangle = 8 units

Area of rectangle

= Length * width

= 8 * 6

= 48 square units
