Question

a rectengular field is of 25m long and 21m wide strip is levelled all around it at the rate of rupees 5 per square meters find the cost of levelling the strip

Answer 1

Answer:

Rs. 2625

Step-by-step explanation:

$\text{Length (l) = 25 m}\\\\\text{Breadth (b) = 21 m}\\\\\text{Area = } l \times b = 25 \times 21 = \boxed{525 \: m^2}\\\\\text{Cost of levelling per meter square = Rs. 5}\\\\\text{Thus, total cost = Rs. 5 } \times 525 = \boxed{\boxed{Rs. 2625}}$

Hope it helps.

Answer 2

Given: Length of the field is 25m, breadth is 21m and the cost of levelling is ₹5/m^2.

To find: The total cost of levelling.

Answer:

First, we will have to find the area.

Formula to find area: Length*Breadth.

Substituting the given values in the formula,

Area = 25*21

Area = 525m^2

Now, cost of leveling per m^2 = ₹5

Therefore, cost of levelling 525m^2 = 525*5 = ₹2625
