You have a square piece of cardboard that measures 14 inches on each side. To build a box, you cut congruent squares out of each corner of the cardboard. Use the picture to find the area of the cardboard you will use to build the box.

ok then as @MelissaHolmes said
OpenStudy (anonymous):
so the original area is 196
OpenStudy (31356):
Okay
OpenStudy (anonymous):
and the area of each little white square that you cut out is 16
OpenStudy (anonymous):
and there are 4 of those squares

OpenStudy (31356):
So 196/16 I think?
OpenStudy (anonymous):
so 16*4
OpenStudy (31356):
Never mind
OpenStudy (anonymous):
so 64
OpenStudy (anonymous):
the total area =14*14=196
the squares=4*16=64
the area =196-64

that's ok
OpenStudy (31356):
I guess so :D
OpenStudy (31356):
So how are we suppose to solve this?
OpenStudy (anonymous):
so you find the area of each of the separate shapes and add them together.
OpenStudy (31356):
Okay
