Asquare and a rectangle have the same area. if the dimensions of the rectangle are 4 ft. by 16 ft., how long is a side of the square? answer options with 5 options a. 10 ft. b. 8 ft. c. 32 ft. d. 6 ft. e. 20 ft.

B
because the area of a rectangle is length times width. 
So 4x16=64
Now we know that a square's area is one of the sides multiplied by itself. 
So we could say its y/\2.
If we set these up to each other since the area of the rectangle is equal to the area of the square. it would look something like this.
64=y/\2 
If we take the square root of both side we would get y=8. 
So one side of the square, y, is a total length of 8.
