in order to find the area of a rectangle you must multiply the base of the rectangle by its height. This is also the same for most polygons

Area of rectangle with part of the shape missing = area of rectangle (lengthxwidth)-area of missing part.

The area of a triangle is expressed using the formula A=(1/2)(bh) Where A is area Where B is length of the base of the triangle. Where H is the height of the triangle. The area of a rectangle is A=BH, Where B is the length of the base of the rectangle. Where H is the height of the rectangle. Because a triangle, essentially, is a half of a rectangle, you find the area of the whole rectangle that the triangle comes from, then divide that in half.
