    the area of the rectangle is 12 * 24 and the triangle area is 0.5 * base * height

    ok so then if we do 36-24 then it is 12

    yea so you now can find the area of the rectangle and area triangle and add them together

    then do we do 12 times 24 to get 288 then and add 12?

    No 288 is the area of the rectangle That is correct Now you need to find the area of the triangle 12 is the length of its base and its height is also 12 so you find the area of triangle using Area = 0.5 * base* height

    yes then add the result to 288 to give you the final answer.

    What is the area of the shaded part of the figure? https://static.k12.com/calms_media/media/1388500_1389000/1388547/1/817a155e30a5af16f0260c998360b83c3a0da25a/62368_FGA_U3_L7_V3_P.jpg A. 324 mm² B. 243 mm² C. 162 mm² D. 81 mm²

    you should be able to do this one using the same formula as the first one The area of the square inside the triangle = 9 * 9' and the area of the triangle = (height * base) / 2 Then to get area of shaded part its area triangle - area of the square

    AS you can see from the diagram the length of the base of triangle = 18 and the height = 8 mm
