Aclose swimming pool is 15 ft wide and 31 ft long the club member want to exposed arrogant border in a strip of uniform width around the pool they have enough material for 312 ft squared how wide can the strip be

The strip can be 3ft wide. You can do find this by finding the area of the whole border section and subtraction the area of the pool to find the area of just the border section. This gives you a trinomial which you can factor to solve for x. I hope this makes sense!

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
