The diagram shows the layout of the township playground. The playground committee is ordering rubber mulch to cover the playground surface. A playground is made up of a rectangle and a triangle. The rectangle has a base of 40 feet and height of 25 feet. The triangle has a base of 22 feet and height of 20 feet. Which shows how to calculate the area of the playground? A = 40 times 25 + one-half (18) (20) A = 40 times 25 + one-half (22) (20) A = 20 times 25 + one-half (25) (20) A = 20 times 18 + one-half (40) (25)
