## Geometry: Common Core (15th Edition)

Find the area of the rectangle. $A=bh=(36)(25)=900$ Given the area of the square, find the length of its sides. $A=s^2$ $900=s^2$ take the square root of each side $\sqrt{900}=\sqrt{s^2}$ $30=s$ Given the side length of the square, find its perimeter. $P=4s=4(30)=120$
