This 4 page lesson includes a page that details the formulas for finding the area of a square, rectangle, triangle, parallelogram and trapezoid. The second and third pages are practice problems. Answer Keys included!
We can find the area of a triangle in different ways depending upon the value given in the problem.The area of triangle formulas is, A=1/2(b*h). Here b is the base of a triangle.h is the height of a triangle.One another way to find the area is the Heron's formula. It gives the area in terms of the three sides of the triangle. It is given by the following formula:
