Question

A track is in the form of ring whose inner and outer circumferences are 88m and

132m respectively find the width of the track

or

A 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 1

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
