Problema Solution
the front of an A frame cabin a national park is in the shape of a triangle, with an area of 315 ft^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
The square area of the face of the A frame is equal to "(1/2)bh" where 'b' is the base and 'h' is the height. Let 'b' represent the base and then '2b-1' represents the height.
315=(1/2)b(2b-1)
b={18,-17.5}
2*18-1 = 35
So the base is 18 feet and the height is 35 feet.
