Question

A rectangular field is 280m long and 100m wide. two cross roads,one parallel to the length of the field and the other parallel to the breadth of the field are constructed at the center of the field. if each of the road are 12m broad,find the areA of cross roads

Answer 1

area of rectangular field= l×b
=280m×100m
=28000 meter square
area of first road=l×b
=12×100=1200 metre square
area of second road= l×b
=12×280
=3360 metre square
area of square so formed =s×s.
=12×12
=144 metre square

area of roads =3360+1200-144
=3360+1056
=4416 metre square
