1.	A track is in the form of ring whose inner and outer circumferences are 88m and132m respectively find the width of the trackorA garden is 90m and 75m broad. A path 5m wide is to be built all around (outside)it along its border. Find the area of path.
Answer» Q2) A garden is 90 m long and 75 m broad. A path 5 m WIDE is to be BUILT outside and around it. Find the area of the path. Also find the area of the garden in a hectare. Length= 90m Breadth= 75m Area of the garden= $l\times bl×b$ =90m+75m=6750m^2=90m+75m=6750m Length of the garden INCLUDING path =90m+5m+5m=100m=90m+5m+5m=100m Breadth of the garden including path =75m+5m+5m=85m=75m+5m+5m=85m Area of the garden including path =l\times b=l×b =100m $\times85m=8500m^2=100m×85m=8500m$ Area of the path= 8500m^2-6750m^2=1750m^28500m Hence, the required area of path= 1750m^21750m and area of the garden= =6750m^2=0.675=6750m =0.675

Q2) A garden is 90 m long and 75 m broad. A path 5 m WIDE is to be BUILT outside and around it. Find the area of the path. Also find the area of the garden in a hectare.

Length= 90m

Breadth= 75m

Area of the garden= $l\times bl×b$

=90m+75m=6750m^2=90m+75m=6750m

Length of the garden INCLUDING path

=90m+5m+5m=100m=90m+5m+5m=100m

Breadth of the garden including path

=75m+5m+5m=85m=75m+5m+5m=85m

Area of the garden including path

=l\times b=l×b

=100m $\times85m=8500m^2=100m×85m=8500m$

Area of the path= 8500m^2-6750m^2=1750m^28500m

Hence, the required area of path= 1750m^21750m

and area of the garden= =6750m^2=0.675=6750m

=0.675
