Area of a triangle
A triangle is a 2-D shape that has 3 sides and angles
In order to determine the area of the shape, we will determine the area of the square circumscribing it first;
Area of the square = 10 * 9 =90 square units
Find the area of the two right triangles
Area of the right triangles = 0.5(10 * 9) + 0.5(9 * 4)
Area of the right triangles = 45 + 18
Area of the right triangles = 63 square units
Take the difference
Area of the given triangle = 90 - 63 = 27 square units
Hence the area of the triangle below is 27 square units
