Question

20. Two roads cross each 3m wide, cut at night angles through the center of a rectangular
park 72m by 56 m, such that each is parallel to one of the sides of the rectangle. What is the
area of the remaining portion of the park?​

Answer 1

Step-by-step explanation:

Area of first cross road which is rectangle = l×b

Hence area =72m×3m=216m

2

Area of 2nd cross road which is rectangle =

=56m×3m=168m

2

Area of middle part which is square =3m×3m=9m

2

Area of cross roads =(216+168)m

2

−9m
