Word Problem: Area of a Triangle

Example: The height of a triangle is 4 inches more than twice the length of the base. The area of the triangle is 35 square inches. Find the height of the triangle.

Example: The base of triangle is 5 units less than twice the height. If the area is 75 square units, then what is the length of the base and the height?

Example: The sides of a triangle are given as 3x, x - 1 and 3x + 1. If the perimeter is 56m, find the area.
