Answers
Answer :
The rate per square meter is Rs. 1.5.
Step-by-step Explanation : (please see the attached file for diagram)
Given : side of square park including path = 30 m
Width of path = 1m
Total cost of covering by Grass = 1176 Rs
To find : Rate per square meter at which the park is covered by the grass.
Side of square park excluding the path is ,
= [30 – (2 x 1)] m
= (30 – 2) m = 28m
Area of remaining part of the park is,
(28)² = 784 m²
Cost of covering the remaining part with grass is Rs. 1176
So,
Area x rate per square meter = 1176
784 × Rate per square meter = 1176.
Rate per square meter = 1176 / 784 = 1.5
Hence, the rate per square meter is Rs. 1.5.
