Question

What is the area of figure ABCD?

Answer 1

Answer: 120

Step-by-step explanation: We can solve this by finding the area of the right triangle and the area of the rectengle and adding both of them. To find the area of the rectengle we use the formula base times height or (b)(h). The base is 13 and the height is 8 so it turns to 8 times 13 which equalls 104. We then need to find the area of the traingle. The formula for that is one half times base times heigt of (1/2)(b)(h). The height of the traingle is the same as the height of the rectengle which is 8 inches. The base of the rectangle is 13 and the base of the rectangle plus the base of the traiangle is 17. To find the base of the traingle we do 17-13 which equalls 4. We then input these numbers into the equation (1/2)(b)(h) which is (1/2)(8)(4) which equals 16. The area of the rectangle (104 inches) plus the area of thetriangle (16 inches) equal 120.
