The answer is 928cm. There are 5 sides. When you find the area of a triangle you multiply base times height then divide by two. But in this case there are two identical triangles so you don’t need to divide. 24x12=288. Then you find the area of the long sides. Multiple 25 and 10 and you get 250. There are two of those sides. Now the last thing to do is find the area of the bottom side. For that one you multiply 14 and 10 and get 140. Now you add all of that together and get 928cm.
Part A: 3x + 15 = 5x - 25
Part B: x = 20
120^ is the answer for this problem
