# Represent the following situations in the form of the quadratic equation.A piece of cloth costs Rs. 200. If the piece was 5 metre longer and each metre of cloth costs Rs. 2 less, the cost of the piece would have remained unchanged.

Let ‘x’ be the length of cloth.

Cost of x metre is Rs. 200.

Cost per metre = Rs. 200 ÷ x

Cost per metre when total size is x + 5 = Rs. 200 ÷ (x + 5)

Cost of 5 metre longer cloth is Rs. 2 less for each metre.
