Question

A rectangular field is 50m long and 45m wide. Find the cost of ploughing the field at 3.50 per square meter​

Answer 1

Step-by-step explanation:

length = 50m

width= 45m

area of rectangular field =l×b

so,

50 ×45=2250m^2

cost =

2250/3.5

= ₹642.85

Answer 2

• Given

• Dimensions of a rectangular field -
• Length of a rectangular field = 50 m
• Breadth of a rectangular field = 45 m
• Cost of ploughing the field per square metre = Rs. 3.50

• To find

• Cost of ploughing the field at the rate of Rs. 3.50 per square meter.

• Concept

• We are having the values of the dimensions of a rectangular field. Firstly, we will find the area of the rectangular field.
• After finding the area we will multiply it by Rs. 3.50 to find the cost of ploughing it.

• Solution

Using formula,

Area of the rectangular field = l × b

where,

• l = length of a rectangular field
• b = breadth of a rectangular field

Substituting the values,

⟶ 50 × 45

⟶ 2250 metre square.

The area of the rectangular field = 2250 m²

Cost of ploughing 1 m² of the field = Rs. 3.50

Cost of ploughing 2250 m² of the field = Rs. 3.50 × 2250 = Rs. 7875

Therefore, cost of ploughing the field = Rs. 7875
