A circular path of width 14 metres surrounds a field of diameter 70 metres.

      

A circular path of width 14 metres surrounds a field of diameter 70 metres. The path is to be
carpeted and the field to have a concrete slab with an exception of four rectangular holes each
measuring 4 metres by 3 metres. A contractor estimated the cost of carpeting the path at sh. 300
per square metre and the cost of putting the concrete slab at sh. 400 per square metre. He then
made a quotation which was 15% more than the total estimate. After completing the job, he
realizes that 20% of the quotation was not spent.

(a) How much money was not spent?
(b) Find the actual cost of the contract
