Question

The length and breadth of a rectangular swimming pool is 2x - 3y and 5x + y
respectively. What is the area of the swimming pool?

Answer 1

Step-by-step explanation:

area of rectangle = length * breadth

length of rectangular swimming pool= 2x - 3y

breadth of rectangular swimming pool= 5x + y

area of rectangular swimming pool= (2x-3y)*(5x+y)

2x*5x +2x*y -3y*5x - 3y*y

$10 {x}^{2} + 2xy - 15xy - 3 {y}^{2} \\ 10 {x}^{2} - 13xy - 3 {y}^{2}$
