Question

A garden is 100 m long and 70 m broad. A path of 3 m wide is built outside and around it. Find the area of path. Also find the area of garden in hectare

Answer 1

Answer:

1.1056m^2. 2.7hectare

Step-by-step explanation:

length(l)=100m

breadth(b)=70m

wide(d)=3m

Now,

Area of path running outside=2d(l+b+2d)

=2*3(100+70+2*3)

=6*176=1056m^2

again,

Area of garden(A)=l*b=100*70=7000m=7hectare

Answer 2

Step-by-step explanation:

let ABCD is the garden

and EFGH is the path

AB=100m

BC=70m

EF=100m+3m+3m=106m

FG=70m+3m+3m=76m

EFGH =106×76=8056m^2

ABCD = 100×70=7000m^2

area of path =8056-7000=1056m^2

area of garden in hectare=

7000÷10000=0.7 hectare
