Question

Find the perimeter and area of rectangular field of length 96 m and breadth 48 m Also find the cost of levelling the field at a 12 per m²​

Answer 1

Given: length = 17 cm, breadth = 13 cm

Perimeter of rectangle = 2 (length + breadth)

= 2 (17 + 13) cm

= 2 × 30 = 60 cm

We know that the area of rectangle = length × breadth = (17 × 13) cm2

= 221 cm2

Answer 2

Given:

• length of the rectangular field = 96m
• Breath of the field = 48m

To Find:

• Perimeter of the field
• Area of the field
• Cost of levelling the field at ₹12/m²

Solution:

Perimeter = 2( length + breath)

Perimeter = 2( 96m + 48m )

Perimeter = 2 ( 144m )

Perimeter = 288m

Perimeter of the rectangular field is 288m

Area = length × Breath

Area = 96m × 48m

Area = 4608 m²

Area of the rectangular field is 4608m²

Cost of levelling 1m² = ₹12

Cost of levelling 4608² = 4608 × 12 = ₹55296

Cost of levelling the field is ₹55296
