Question

a rectangle park has dimension 90m by 70m. Two paths in parallel to the lengths of the rectangle and two paths run parallel to its. breadths. The two paths along the length are 7 m wide and the other two along the breadth are 5 m wide. Find the area of: (a) all the paths (b) the remaining portion of the park​

Answer 1

Answer:

(a) 1,820m² (b) 4,480

Step-by-step explanation:

Area of the two paths along the length =2×(90+7)

= 1,260m²

area of the two path along the breath = 2×(70+5)m

= 700m²

area of the paths crossing each other = 4×(7×5)m

= 140m²

Therefore, total area of the path= (1260+700-140)m²

= 1,820m²

Area of the park = 90×70m = 6300m²

Therefore, area of the remaining portion= (6300-1,820)m² = 4,480m²
