A. well, to find the perimeter of a rectangle, it is 2(length+width) using this, the perimeter of the tennis court is 2(2x+6+x)=2(3x+6)=6x+12 the perimeter of the basketball court is 2(3x-14+1/2x+32)=2(2 1/2x+18)= 5x+36 B. the difference is subtraction, so it'd be 6x-12-(5x+36) C. width is 2x+6 2x+6=36 2x=30 x=15 tennis: 15 by 36 basketball: 3*15-14= 31 1/2*15+32= 39.5 31 by 39.5
