Step-by-step explanation:
The two cross roads cut the park into four equal smaller rectangle parks.
Find the dimensions of one smaller park
Length= (70-5)÷ 2 = 32.5m
breadth=(50-5)÷2 = 22.5m
Find the area of one smaller park
Area=Length × breadth
Area= 32.5×22.5 = 731.25m²
Find the area of four smaller parks
Area of 1 park = 731.25m
Area of 4 park= 731.25×4 = 2925m²
Area of remaining park = 2925m²
