Question

The perimeter of a rectangle deck is 92 feet. The length is 11 less than the width. Find the dimensions of the rectangle.

Answer 1

let x be the width
x-11 is the length

the perimeter is 92

P=x+x+(x-11)+(x-11)

this means, perimeter is the addition of all sides

so P=92

92=x+x+(x-11)+(x-11)

solve for x
