The rectangle is made up by the lines x = 3, x = 8, y = 8 and y = -1. A rectangle with sides a and b has area A = a*b.
To find the area of the rectangle in the problem, first determine the length of its sides.
As a pair of opposite sides is x = 3 and x = 8, the length of one of its sides is 8 - 3 = 5. The other side has length 8 + 1 = 9.
The area of the rectangle is 9*5 = 45 square units.
The area of the rectangle is 45 square units.
