Question

A walk 2m, wide surrounds a rectangular grass plot 28m. long and 11 m, wide. Find

the area of the walk.
The area of the walk is.

Answer 1

The area of the walk is 480 square meter.

Explanation:

Given,

Length of rectangle = 28m

Width of rectangle = 11m

Now, if a person walk 2m away from the rectangular surrounding, it will add 4m (2m at the top and 2m at the bottom) to the length of rectangular.

Hence, the length (l) of walking path would be 28+4 = 32 m

Similarly, the width (w) will also increase by 4 = 11 + 4 ? 15 m

The formula of area = l x w

area = 32 x 15

area = 480 square meter.

Hence, the area of the walk is 480 square meter.
