## anonymous one year ago If a rectangle has a perimeter of 70, a length of x and a width of x - 9, find the value of the length of the rectangle.

Perimeter is sum of length and width: $$\text{length}+\text{width}=x+(x-9)=70$$ Solve for x, then length = x.

Thanks!

Perimeter is sum of twice width + twice length

2x+2x-18=70

That is true! Thank @Mertsj
