Answer 2

Answer:

If 200 students are given cloth pieces of size 20 cm × 25 cm, then the total cost of cloth at the rate of Rs.50 per m²​ is Rs 500.

Step-by-step explanation:

Given:

Total number of student = 200 students

Dimension of cloth = 20 cm × 25 cm

Rate of cloth = Rs.50 per m²​

Find the total cost of cloth.

Formula area of rectangle = length × breadth

Step 1: Find the area of cloth and area of the total cloth.

20 cm = 0.20 m and 25cm = 0.25 m

area of cloth = length × breadth=  0.20 m × 0.25 = 0.05 sq. m

So, total cloth for 200 student = 200 × 0.05 = 10 sq. m

Step 2: Find the total cost of cloth at the rate of Rs.50 per m²​.

The total cost of cloth at the rate of Rs.50 per m²​ = 50 ×10 sq. m = Rs 500.
