Question

A 3m wide path runs inside a square park of side 90m.Find the area of the path.Also finds the costs of cementing it at the rate of RS 104 per sq.m​

Answer 1

Step-by-step explanation:

Area is l×b = 270m²

Now 1m² = 104ts

So 270×104 = 28,080 rs for the park

Answer 2

Given ABCD is a park of [side = 9cm ]

now

Portion outside (EFGH) is a running path of width = 3m

area of running path = area of ABCD - area of EFGH

length of side EFGH =90−6=84cm

Then

area of running path =(90)^2-(84)^2

Area=8100−7056

Area=1044cm
