<h3>What is a rectangle?</h3>
A rectangle is a plane shape that has pair of opposite sides equal and parallel.
To find the equation that could be used to find the area of the walkway, we use the formula below.
Formula
- Area of the walkway(A) = Area of the swimming pool and the walk- area of the swimming pool
- A = [(h+3)(b+3)]-(hb)
- A = hb+3h+3b+9-hb
- A = 3h+3b+9.
Hence, The equation that can be used to find the area of the walkway is A = 3h+3b+9
