The width of a pool is x meters long. The length of the pool is four meters longer than the width. Write an expression that represents the area of the pool.

(x² + 4x )m²

Step-by-step explanation:

The width of a pool is x meters long. The length of the pool is four meters longer than the width.

= x + 4 m

Write an expression that represents the area of the pool.

The shape of the pool is rectangular.

Formula = Length × Width

Hence, an expression for the area of the pool

= x + 4 m × xm

= x( x + 4)

= (x² + 4x )m²
