The base of a parallelogram is (2+3)units and the corresponding height is (2−3)units.Find the area of the parallelogram in terms of .What will be the area of the parallelogram if =units?

Respuesta :

Answer:

In terms of x, the area is given by: [tex]A = 4x^2 - 9[/tex].

If x = 30 units, the area will be of 3591 units squared.

Step-by-step explanation:

Area of a parallelogram:

The area of a parallelogram of base b and height h is given by:

[tex]A = bh[/tex]

In this question:

We have that [tex]b = 2x + 3, h = 2x - 3[/tex].

So

[tex]A = (2x + 3)(2x - 3) = 4x^2 - 6x + 6x - 9 = 4x^2 - 9[/tex]

In terms of x, the area is given by: [tex]A = 4x^2 - 9[/tex]

If x = 30 units:

[tex]A = 4*30^2 - 9 = 4*900 - 9 = 3600 - 9 = 3591[/tex]

If x = 30 units, the area will be of 3591 units squared.
