Answer:
The area of both roads = 411m²
Step-by-step explanation:
area of first road = road width × rectangle's length
= 3m×80m
= 240 m²
area of second road = road width × rectangle's width
= 3m×60m
= 180m²
area of square which is at middle = 3×3 m
= 9m²
total area of roads = area of first road + area of second road - square are of road
= 240m²+180m²-9m²
= 420m²-9m²
= 411m²
hope it helps.

Answer:
236 m²
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
