Question

Lesson 8: Geometric Constructions

Madelyn had a square piece of cardboard that was 10 inches in length. She cut one 3-inch square from each corner. The shaded part represents the remaining cardboard. Show your work!

Answer 1

When you figure out what your question is, you can probably answer it yourself.

maybe something like shaded/total = (4*3^2)/(10-2*3)^2

Answer 2

As + Ac = 10*10 = 100 in^2.
As = 100 - Ac = 100 - 4*(3*3) = 64 in^2 = shaded area.
Ac = Area cut.
