Tommy's mother lets him ride his bike 2 blocks north of his block, 3 blocks east, 2 blocks west, and 2 blocks south. His friend's father lets his friend ride his bike 80 square blocks. How many times greater is the area his friend can ride in compared to Tommy?
Tommy's area is 5 blocks wide because 3 + 2 = <<3+2=5>>5
His area is 4 blocks tall because 2 + 2 = <<2+2=4>>4
The total area is 20 square blocks because 5 x 4 = <<5*4=20>>20
His friend's area is 4 times bigger because 80 / 20 = <<80/20=4>>4
