Question

The base of a parallelogram is (3x + 1) units and the corresponding height is (7x - 4 units). Find the area of the parallelogram in terms of x. What will be the area of parallelogram if x = 20 units?

Answer 1

Step-by-step explanation:

Area of Parallelogram = base X height

= (3x+1)(7x-4)

= 21x²-12x+7x-4

= 21x²-5x-4

When x=20 units

area = 21(20)²-100-4

= 8400-100-4

= 8300-4

=8296 unit²
