Area of the figure is 135cm²
Given:
length of the base : 15 cm
height of the figure : 13 cm
height of the triangle : 8 cm
Area of the rectangle = Length x width
Width = height of the figure - height of the triangle
= 13 cm - 8 cm
Width = 5 cm
Area of the rectangle = 15 cm x 5 cm = 75 cm²
Area of the triangle = height x base x 1/2
= 8 cm x 15 cm x 1/2
= 120 cm² / 2
Area of the triangle = 60 cm²
Area of the figure = Area of Rectangle + Area of Triangle
= 75 cm² + 60 cm²
Area of the figure = 135 cm²
