Answer 1

Answer:

Step-by-step explanation:

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
