What is the cost of tiling a rectangular plot of land 500 m long and 200 m wide at the rate of ? 8 per hundred sq. m? Class 6

Question 1.

What is the cost of tiling a rectangular plot of land 500 m long and 200 m wide at the rate of ₹ 8 per hundred sq. m? Class 6

Solution:

Area of the rectangular plot of land = 500 × 200 sq. m.

= 100000 sq. m.

So, cost of tiling at the rate of ₹ 8 per 100 sq. m.

= ₹ [latex]\frac{100000}{100}[/latex] × 8 = ₹ 8000.

Question 2.

A rectangular coconut grove is 100 m long and 50 m wide. If each coconut tree requires 25 sq. m, what is the maximum number of trees that can be planted in this grove? Class 6

Solution:

Area of the rectangular coconut grove = 100 × 50 sq. m.

= 5000 sq. m.

In 25 sq. m, 1 tree can be planted.

So, in 1 sq. m, [latex]\frac{1}{25}[/latex] can be planted.

Hence, in 5000 sq. m, number of trees that can be planted = [latex]\frac{1 \times 5000}{25}[/latex] = 200.
