Question

Describe in words how you calculated the area of each shape. Be sure to include
which formulas you used. For which polygon(s) did you compose a rectangle to find
the area? Which polygon(s) did you decompose into simpler shapes? Which simple
shapes did you use


i used a triangle, square, and 2 right riangles to make a square so it is still a square lol


For the triangle I used the expression b x h x 1/2, base is 8 and height is 5 so
8 x 5 x 1/2 = 20
For the square I used the expression l x w, length is 6 and width is 5 so
6 x 5 = 30

Answer 1

Then I composed a rectangle for the square by using two right triangles. Each right triangle had a base of 5 and a height of 2.5, so the area of each right triangle was 5 x 2.5 x 1/2 = 6.25. Since there were two right triangles, the total area of the square was 30 + 6.25 + 6.25 = 42.5.

For the polygon that I decomposed into simpler shapes, I used the square. I decomposed it into two right triangles and a rectangle. I calculated the area of each smaller shape separately and then added them together to find the total area of the square.
