Answer 2

The area of the road is 411 m².

Step-by-step explanation:

Consider the provided information.

It is given that two crossroad each of width 3 m, run at right angles and parallel to the sides of a rectangular plot of dimensions 80×60 m.

Now consider the figure:

The area of road = Area of IJKL + Area of EFGH - Area of PQRS

For the rectangle IJKL the length is 60 m and breath is 3 m.

For the rectangle EFGH the length is 3 m and breath is 80 m.

For PQRS the length and breath is 3 m.

The area of road = 60×3 + 3×80 - 3×3

The area of road = 180 + 240 - 9

The area of road = 411 m²

Hence, the area of the road is 411 m².
