Question

What is the area of a rectangle whose side are x – 3 and x + 5?

Answer 1

Given :

• The sides of a rectangle are (x - 3) and (x -5).

To Find :

• The area of the rectangle.

Solution :-

Here we are given two sides of rectangle . We know that the area of rectangle is ,

→ Area = side 1 * side 2

Substituting the respective values ,

→ A = (x-3)(x+5)

→ A = x(x+5) -3(x+5)

→ A = x² + 5x -3x -15

→ A = x² +2x - 15

Hence the area of the rectangle is x² +2x -15.
