Reuben Cram pg 92 q.4

I know I didn't ask to do this scribe but I lost my other one and need to catch up.
4. what are the areas of the three squares shown.



e-30mm. To find the area of this square you need to times the number by itself to get it. 30 is 900mm2.
f-40mm. Now find the area of this square to get 1600 mm2
g-Now for the hypotenuse 50mm. 2500mm2. But now you have to know if it is a right triangle. Add the legs value together to get the hypotenuse. If you get the hypotenuse comment me that it was right and tell me how to paste a pic because I have no idea how to do it.
