The area of a triangle is given by:
= 558 sq. ins.
The height, h = b-5 Substitute this into the above equation and solve for b.
Multiply both sides by 2
Subtract 1116 from both sides and simplify.
Solve by factoring.
Apply the zero product principle.
and/or
If then This is a valid solution since it is positive.
If then Not a valid solution since the length of the base must be a positive value.
The length of the base is 36 inches.
