There are 2 questions.?

An oblong garden measures 60m by 55m.From the centre of each side,a path 2m wide goes across to the centre of the opposite side.Find the area of the paths?

A rectangular piece of ground is 45m long and 30m wide.It has 2 sides each 1m wide,running midway within it,one parrellel to the breadth.Find the area of the roads.Also calculate the area of the remaining ground.

There are 2 questions.?
Question 1:



2 x 60 = 120m^2

2 x 55 = 110m^2



if we want total area taken up by the paths, note that they overlap in the middle (the overlap area is 2 x 2 = 4m^2).. so..



120 + 110 - 4 = 226m^2



Question 2:



not sure i understand the question.. running midway within it?



if i understand right, you're splitting this area in 2 with two 1m paths running across.. that would just be 2 x 30 = 60m^2 is the area of the paths, and 45 x 30 - 60 = 1290 = total area of the ground minus the 'roads'
Reply:Ans 1. 126 Sq Mtrs.



Ans 2. 74 Sq Mtrs
Reply:60*2+55*2-2*2=226
