Question

What is the area of this compound shape?!

Answer 1

So you would start with the square and do 18 times 18 which equals 324 then for the triangle it's base times height divided by two so 9 times 18 divided by 2 which equals 81 then you add the triangle plus the square and your final answer is

answer:405

Answer 2

First you have to find the area of the triangle. To do this you must us the formula 1/2 multiplied by the base and height of the triangle. In this case the equation would be: 1/2 (or 0.5) x 18 x 9 which equals 81. Then you would have to find the area of the square, which is base times height which would be: 18 x 18. This would equal 324. To get your final answer you need to find the product of the two areas which would equal 405.
