Question

A grassy plot measures 80m by 60m. From the centre of each side, a path 4m wide goes across to the centre of the opposite side. Find the area of the paths.​

Answer 1

Answer:

Step-by-step explanation:

If two cross roads each of width 'w' units , run at right angles through the centre of rectangular path of length 'l' units and breadth 'b' units , then

the area of total path =(width of path)(length of the park + breadth of the park -width of path)

=w(l+b-w)

Using this formula

From given data

l=100m

b=80m

w=5m

Area of the total path=w(l+b-w)

=5(100+80-5)

=5×175

=875 square meters
