I need help
Casey was building a rectangular pen for his pigs. He has 62 feet of fencing. The length of his pen is 9 feet longer than the width. Write and solve an equation to find the dimensions of the pen.

Answer 1

let the width by w

so the length is w + 9

so the perimeter is

62 = 2w + 2l

or

62 = 2w + 2(w + 9)

simplify the equation and then solve for w

Answer 2

11 feet by 20 feet.

Answer 3

2x+2(x+9)=62
OR 4x+18=62

The dim. of the pen are 11 feet by 20 feet
