Question

The rectangle below has an area of 81-x^281−x 2 81, minus, x, squared square meters and a width of 9-x9−x9, minus, x meters. What expression represents the length of the rectangle?

Answer 1

Length = 9 + x meters

Explanation:

The rectangle below has an area of 81- x² square meters and a width of 9-x meters. What expression represents the length of the rectangle?

Area of a rectangle = Length × Width

Area = 81 - x²

Width = 9 - x

Hence

Length = Area /Width

= 81 - x²/9 - x

= 9 + x meters
