Problema Solution

The front of an A-frame cabin in a national park is in the shape of a triangle, with an area of 33ft^2. If the height is 1 ft less than twice the base, find the base and the height of the front of the cabin.

Answer provided by our tutors

Let


x = the base of the triangle, x>0


h = the height of the triangle, h>0


A = 33 ft^2 is the area of the triangle


The height is 1 ft less than twice the base:


h = 2x - 1


The area of the triangle is:


A = (1/2)xh


Plug the values for A and h = 2x - 1 into the last equation:


(1/2)x*(2x - 1) = 33

x = 6 ft


h = 2*6 - 1


h = 11 ft


The base is 6 feet.


The height is 11 feet.
