Answer:
total area = 1000 yd^2
Step-by-step explanation:
you will have to break up the area into multiple shapes.
I broke it up into two rectangles and a triangle.
one rectangle is w = 40 and l = 10
the second rectangle is w = 20 and l = 20 (l = 30-10 because that is part of the other rectangle's area)
the triangle is b = 20 and h = 20 (b = 40-20 because that is part of the other rectangle's area and h = 30-10 because that is part of the other rectangle's area)
the area of a rectangle is l x w = A
the area of a triangle is 1/2 x b x h = A
then, all of the areas added is the total area:
rectangle one + rectangle two + triangle = total area
(40 x 10) + (20 x 20) + 1/2 x (20 x 20) = 1000 yd^2 (don't forget to square the yards)
