The areas of similar triangles abc and def are equal. if the longest side of def measures 25 units, what is the length of the longest side of abc

Since the triangles are similar the answer would have to be 25 units.

The answer is d. 16^2 + 63^2 = x^2hope this .

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
