Question

A square grassy plot is of side 100 metre.It has a gravel path 10 metres wide all round it on the inside. Find the area of path.​

Answer 1

Step-by-step explanation:

side of grassy plot = 100 m

area of grassy plot = 100^2

= 10000 m^2

since it has a gravel path of 10 m width, we have a square of side 80 m inside

area of plot inside the grassy plot = 80^2

= 6400 m^2

so the area of gravel path = 10000 - 6400

= 3600 m^2
