Question

Find the cost of fencing a rectangular field 54 metre long and 38 metre wide with steel wire at rupees 1.50 per metre.​

Answer 1

Answer:

Given :-

• A rectangular field is 54 m long and 38 m wide with steel wire at Rs 1.50 per metre.

To Find :-

• What is the cost of fencing a rectangular field.

Formula Used :-

✪ Perimeter of a rectangle = 2(L + B) ✪

where,

• L = Length
• B = Breadth

Solution :-

Given :

• Length = 54 m
• Breadth = 38 m

According to the question by using the formula we get,

↦ Perimeter = 2(L + B)

↦ Perimeter = 2(54 + 38)

↦ Perimeter = 2(92)

↦ Perimeter = 2 × 92

➠ Perimeter = 184

Hence, the perimeter of a rectangle is 184 m .

Now, we have to find the cost of fencing a rectangular field,

Given :

• Perimeter = 184 m

If, 1 m of steel wire cost Rs 1.50 per metre

Then, 184 m of steel wire = 184 × 1.50 = Rs 276

∴ The cost of fencing a rectangular field is Rs 276.

Answer 2

Answer:

Cost of fencing the rectangular field = Rs 276

Step-by-step explanation:

Given: Length of rectangular field = 54 m

And its Breadth = 38 m

Cost of fencing with steel wire = Rs 1.50/m

Formula to find Perimeter of rectangle:

= 2(Length + Breadth) unit

= 2(54 + 38) m

= 2 × 92 m

= 184 m

Now,

Find cost of fencing the rectangular field:

1 m of steel wire cost = Rs 1.50

184 m of steel wire cost = Rs 1.50 × 184

= Rs 276
