Question

there is a rectangular garden have length 80m and breadth 60m a road width 5m and rounded it's out side.find the area of road​

Answer 1

Answer:

The area of the road is 1500 sqm

Step-by-step explanation:

I am assuming that "and rounded it's out side" in the sum should reach "all around its outside."

Length of garden = 80m; Breadh of garden = 60m

Area of garden = 80 * 60 sqm = 4800 sqm

Now, there is a road of 5m on all sides of the garden. Hence, if you imagine the garden and the road as one LARGE rectangle. It will have

Length = 80 + 5 + 5 = 90m

Breadth = 60 + 5 + 5 = 70m

Area of this large rectangle = 90*70 sqm = 6300 sqm

Clearly, the difference between this large rectangle and the garden is actually the area covered by the road.

Area of road = Area of large rectangle - Area of garden

                      = 6300 sqm - 4800 sqm

                      =  1500 sqm

sqm = square meter = 1m x 1m
