Question

find the cost of fencing a square garden of side 30 ft at a rate of 83 per sq cm

Answer 1

Given: Side of the square garden is 30ft and cost of fencing is Rs. 83/cm^2

To find: Total cost

Answer:

Perimeter of a square = 4*S

S = 30ft

Therefore perimeter = 4*30 = 120ft

To convert feet to centimeter, multiply it by 30.48.

120*30.48 = 3657.6cm

Cost for fencing 1cm = 83

Therefore cost for fencing 3657.6cm = 83*3657.6 = Rs. 303580.8

Hope it helps :)

Answer 2

Given : cost of fencing a square garden of side 30 ft at a rate of 83 per sq cm.

Find: Total cost

Solution :

Perimeter of square = 4×S

S = 30ft.

So,

Perimeter of square = 120ft.

Now,

Converting feet into centimeter, we will multiple it by 30.48

=> (120×30.48)cm.

=> 3657.6cm

Now,

Cost for 1cm of fencing = ₹83

So, the cost of 3657.6cm =₹ (83×3657.6)

So, the cost of 3657.6cm =₹ (83×3657.6) =₹ 303580.8
