The sixth grade garden at Sunnyside School is 14/3 yards long and has an area of 56/9 square yard. How wide is the garden?

Can someone check my answer? you : )

Iknow the square root of 2 is irrational

You work for a landscape company that just got a contract to re-mulch a park. the area that needs mulching is 30 feet by 60 feet. they want a 3 inch layer of much on the area. the company has bags of mulch that cover 2 cubic yards that cost $4.00 per bag. how much will it cost the consumer just in materials to re-mulch the area (round to the nearest dollar)?
