Answer 1

Answer:

A rectangular garden 120m long and 65m broad a path of uniform width of 5m has to be constructed around it on its outside find the cost of gravelling the park at rupees 11.40 per metre.

Answer 2

Answer:

Cost of the gravelling the path = ₹22230

Step-by-step explanation:

$❍ \:\large\bf{Correct \: Question}$

1. A rectangular garden 120m long and 65m broad a path of uniform width of 5m has to be constructed around it on its outside find the cost of gravelling the park at rupees 11.40 per metre²

$\large\bf{❒ \: Given}$

• Length of the Garden = 120m
• Breadth of the Garden = 65m

$\large\bf{❒ \: To \: Find}$

• Cost of gravelling the path at 11.40m²

$\large\bf{❒ \:Solution }$

Area of the garden = Length × Breadth

Area of the garden

= (120 × 65) m²

= 7800m²

Length of the garden including the path

= 120m + (5m + 5m)

= 120m + 10m

= 130m

Breadth of the garden including the path

= 65m + (5m + 5m)

= 65m + 10m

= 75m

Area of the garden including the path

= (Length × Breadth)

= (130 × 75) m² = 9750m²

∵ Area of the path = (9750 - 7800) m² = 1950 m²

Cost of the gravelling the path = ₹(1950 × 11.40)

= ₹22230

• Area of a Square = side × side
• Area of a Triangle = $\rm\frac{1}{2}× b × h$
• Area of a circle = πr²
