Question

Hey... hey you.. psstt... can you help me in this exercise pls? It would mean everything.

Answer 1

I am guessing this is area it’s 123 cm

Answer 2

55.5.

Since this is an irregular figure and you’re trying to solve for area, you would need to split it up into shapes, i.e. a rectangle and a triangle. You have the length and width of the rectangle, so in line with the area formula flr a rectangle: l•w=A, you would need to multiply 3 and 5 to get 15. As for the area of the triangle, you can see that it was a height of 9, because of the 3 inches you shave off, and a length of 9. To get the area of a triangle, multiply the length times the width and divide by 2. So (9•9)/2. That would give you 40.5, which you then add to 15 to get 55.5.
