Answer:
247cm^2
Explanation:
Construct a formula to find the total area of the figure. To do that first figure out what shapes are in the given figure. In this case there are 2 triangles each with a height of 4cm and a base of 10cm, 1 sqaure with a width of 9cm and a length of 5cm, 1 square with a width of 9cm and a length of 8cm and one last square with a width of 9cm and length of 10cm.
The formula for the area of a triangle is A=(1/2)(b)(h) and the fromula for the area of a sqaure is A = L*W.
The total area: A = (4)(10)+(9)(5)+(9)(8)+(10)(9) = 247cm^2
