Question

8. A lawn 50 m long and 40 m broad has a path of uniform width 8 m outside it.
Find the area of the path and the cost of levelling it at the rate of 50 per
square metre.​

Answer 1

Answer:

59,200 rupees

Step-by-step explanation:

area of rectangle - l x b

where l -  length - 50

and b - breadth - 40

50 x 40

= 2000 sq m

area of smaller rectangle - length - {8+8} x breadth - {8+8}

= 50 - 16 x 40 - 16

= 34 x 24

=816 sq.m

area of path - 2000- 816 = 1184

1184 x 50 = cost

= 59 , 200 rupees
