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
i think u are in 7th or 8th class. u must use ur brain for these silly questions.
