Question

A rectangular field is 36m long and 22m
wide. It has two cross roads, one parallel to
its length and the other parallel to its width.
Find the area of cross roads if each is
1.5m wide.​

Answer 1

from the figure cross roads are in rectangle shape

area of rectangle = l×b

ar( first road) =36×1.5

=54m square

ar(second road )=l×b

=22×1.5

=33

but the two roads intersect at a point so we have to subtract that area54+33=87

87-(1.5×1.5)

87-2.25

84.75
