Question

A rectangular lawn measuring 50m by 36m is surrounded externaly by a path which is 2 m wide. Find the area of the path. Also calculate the cost of levelling of the path at Rs16 per metre ².​

Answer 1

Answer:

360 m², ₹ 5760

Step-by-step explanation:

Given:

• Length of rectangular lawn = 50m
• Breadth = 36m
• Width of externaly surrounding path = 2m

To Find:

• Area of the path
• Cost of levelling of the path at Rs 16/m²

Solution:

Area of path = 2x(length + breadth + 2x)

where, x = width of the path.

= 2×2(50+36+2×2)

= 4 (50+36+4)

= 4 × 90

= 360 m²

Cost of levelling the path = Area of path × cost rate of levelling

= 360 × 16

= ₹ 5760
