Answer:
Area of cross roads= area of vertical road+ area of horizontal road - area of intersection of two roads
Area of cross roads=(22×2.5)+(30×2.5)−(2.5×2.5)m

Answer:
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
