To find the area of the polygon, we first need to find the areas of the square and the triangle separately, and then add them together.
Square:
The area of a square is given by the formula A = s^2, where s is the length of one side of the square. In this case, the side length of the square is 10 cm. So, the area of the square is A = 10^2 = 100 square cm.
Triangle:
The area of a triangle is given by the formula A = 0.5 * base * height. In this case, the base of the triangle is 7 cm and the height is 20 cm. So, the area of the triangle is A = 0.5 * 7 * 20 = 70 square cm.
Adding the areas of the square and the triangle together:
Total area = area of square + area of triangle
Total area = 100 + 70 = 170 square cm
Therefore, the area of the polygon is 170 square cm.
What is the area of the polygon below in square units? The polygon is 10 cm 7 cm and 20 cm The polygon is a square with a triangle on top
