Question 766662
x = length
(2/3)x = width


Perimeter of a rectangle is 2(length) + 2(width)


2x + 2(2/3)x = 80   {perimeter is 2(length) + 2(width)
2x + (4/3)x = 80 {multiplied}
(10/3)x = 80 {combined like terms}
x = 24 {divided each side by 10/3}
(2/3)x = 16 {substituted 24, in for x, into (2/3)x}


length is 24 
width is 16
