Question

ucting the path is 10 x 5000 = 350 000.
9 Two roads, each 3 m wide, run at right angles through the middle of a rectangular
park such that each is parallel to one of the sides of the park. If the park is 70
by 45 m, find the area of the portion of the park minus the path.
​

Answer 1

Answer:

Rs. 57750

Step-by-step explanation:

Length of the 1st cross road parallel to the length = 70 m

Breadth of the 1st cross road parallel to the length = 5 m

Area of the 1st cross road = 70*5  

= 350 sq m

Length of the 2nd cross road parallel to the breadth = 45 m

Breadth of the 2nd cross road parallel to the breadth = 5 m

Area of the 2nd cross road = 45*5  

= 225 sq m

Area of the common part of the 2 cross roads with width 5 m that lies at the center of the rectangular park = 5*5

 = 25 sq m

Area of the 2 cross roads = Area of the 1st cross road + Area of the 2nd cross road - Common area

⇒ (350 + 225) - 25

⇒ 575 - 25  

= 550 sq m

Cost of constructing the roads = Rs. 105 sq m

Total cost of constructing the road = 550*105
