Question

Hailey is going to paint a wall in her bedroom. The bottom part of the wall is a rectangle (16ft. x 18ft.), and the top part is a triangle (8 ft. high x 18ft. long). What is the total area of the wall?

Answer 1

Area of wall = 360 ft²

Explanation:

Given:

One part of wall (Rectangle) = 16ft x 18ft

Another part of wall (Triangle) = 8ft x 18ft

Find:

Area of wall

Computation:

Area of wall = Area of rectangle + Area of triangle

Area of wall = (l x b) + (1/2)(b)(h)

Area of wall = (16 x 18) + (1/2)(8)(18)

Area of wall = 288 ft² + 72 ft²

Area of wall = 360 ft²
