So first let’s find the area of the rectangle. The formula for finding the area of a rectangle is A=l x w. The length is 10ft and the width is 8ft. A=10ft x 8ft=80ft^2 The area of the rectangle is 80ft^2.
Now let’s find the area of the triangle. The formula for finding the area of a triangle is A=h x b/2. Both the height and the base of the triangle is 4ft. A=4ft x 4ft/2=8ft^2. The area of the triangle is 8ft^2.
Now to find the area of the entire shape. Add the area of the rectangle and the area of the triangle. 80ft^2+8ft^2=88ft^2 The total area of the shape is 88ft^2.
