The height of a triangular window is 3 feet less than its base. the area the window is 20 ft.? find the dimensions of the window

Let us assume base of the window = b feet.

Height is 3 feet less than base, that is = (b-3).

Given area of the triangle = 20 feet square.

We know formula for area of a triangle:

Area = × Base × Height

Plugging values in formula, we get

20 =

Factoring quadratic, we get

=0

b+5=0

b=-5

b-8=0

b=8.

For base we can take only positive value.
