Ok lol can I see some other things that
132! Read on for explanation..... So first step is to choose which to solve (either way works) for example let’s start with the base, the base is a square and a square will always have to the same measurements on each side so for the base you find your measurement, which is 6, so you multiply 6 by 6 to get 36, then you move on to the triangles, for the triangles it’s also asking the same thing as the base, but now it’s asking for the height and the base which the height is 8 and the base is 6, so you multiply those two numbers and get 48 BUT you also have to multiply 48 by 1/2 because the formula for a triangle is A = BH1/2 so 48 multiplied by 1/2 is 24 and instead of doing this for each side, you can simply multiply 24 by 4, because there are 4 triangles that make that shape complete, so 24 times 4 is 96, now you have add the sums, 96 plus 36 equals 132. and don’t forget to put 132 square ft.
