In the first grid more squares are shaded than in the 2nd grid.
Answer: -11x+15
Step-by-step explanation: distributed property: 2x+2-3x-7-10x+20, -11x+15
It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.
The area of a square is given by the equation
where s is the length of the side.

A=576
The area of this square is 576cm2.
Hope this helps!
