Question 406726
"A pasture is twice as long as it is wide. Its area is 115,200 ft square. How wide is the pasture?"


x = width
2x = length {it is twice as long as it is wide}


Area of a rectangle = length x width


x(2x) = 115,200 {substituted into area formula}
2x^2 = 115,200 {multiplied x by 2x and added exponents}
x^2 = 57,600 {divided both sides by 2}
x = 240 {took square root of both sides}


width = 240 ft
