1.	Two cross roads each two metre wide, runs at right anglesthrough the centre of a rectangular park 72 m by 48 m, suchthat each is parallel to one of the sides of the rectangle. Findthe area of the remaining portion of the park.
Answer» Area of first crossroad which is rectangular = l×b Hence area = 72m × 2m= 144 m² Area of 2nd crossroad whuch is rectangular = 48m× 2m= 96 m² Area of middle part which is square =2m×2m= 4m^2 Area of crossroads= (144+96) m² - 4 m² =240 m² - 4 m²= 236 m²

Two cross roads each two metre wide, runs at right anglesthrough the centre of a rectangular park 72 m by 48 m, suchthat each is parallel to one of the sides of the rectangle. Findthe area of the remaining portion of the park.

Answer»

Area of first crossroad which is rectangular = l×b

Hence area = 72m × 2m= 144 m²

Area of 2nd crossroad whuch is rectangular = 48m× 2m= 96 m²

Area of middle part which is square =2m×2m= 4m^2

Area of crossroads= (144+96) m² - 4 m²

=240 m² - 4 m²= 236 m²
