Geometry word problem help?

• I was working on my homework and came across these two problems that I don't understand. Can anyone help and explain to me on how to solve them? 1. A security fence is to be built around a 346 m by 76 m field. Fence wire will cost $2.56 per meter. What will the wire cost? Hint: The perimeter is 844 meters. 2. The backyard of a new home is shaped like a trapezoid with a height 46 ft. and 105 ft. What is the cost of putting sod on the yard if the landscaper charges $0.26 per square foot for sod?

• Answer:

  1. A security fence is to be built around a 346 m by 76 m field. Fence wire will cost $2.56 per meter. What will the wire cost? Hint: The perimeter is 844 meters. This question basically answers itself for you. The security fence is built around the field, meaning the fence IS the perimeter. So, you multiply $2.56 by the length of fence in meters that you need, and you get $2160.64. 2. The backyard of a new home is shaped like a trapezoid with a height 46 ft. and 105 ft. What is the cost of putting sod on the yard if the landscaper charges $0.26 per square foot for sod? I'm sorry, but maybe you have a typo or something in the question? In order to find the area of a trapezoid you need the lengths of both bases and the height.
