The perimeter of a rectangular garden is 240 feet. If the length of the garden is 69 feet, what is its width?
Naddika [18.5K]

Perimeter of rectangle: P=2a+2b

Put in data given a=69 (height) and P=240 (perimeter)

240=2\times69+2b

Now solve for b (width).

2b=240-2\times69

b=\frac{240-2\times69}{2}=\boxed{51}

It's width is 51 feet. Hope this helps.
