Question

A rectangular park has length 25m and breadth 15m. Find its perimeter. Calculate the cost of fencing the park at the rate of Rs. 35 per metre.

Answer 1

Answer:

Length of Rectangle = 25m

Breadth of rectangle = 15m

The perimeter of rectangle = 2(l+b) = 2(15m +25m) = 30m + 50m = 80 m

Cost for 1m is rs 35

Cost of 80m is 80×rs 35 = rs 2800

$\large\underline{\underline{ \sf \maltese{To\:Find}}}$

its perimeter and Calculate the cost of fencing the park at the rate of Rs. 35 per metre.

__________________________________________

$\large\underline{\underline{ \sf \maltese{\:Solution:-}}}$

$\sf\purple{length:}$ 25m

$\sf\pink{breadth:}$ 15m

⟹ perimeter = 2(length + breadth)

⟹ perimeter = 2(25+15)

⟹ perimeter = 2(40)

⟹ perimeter = $\mathbb{\pink{\boxed{80cm}}\star}$ 25m

★cost of fencing:

➠Rs. 35 per metre.

➠so cost of fencing for 80m = 80×35 Rs

➠cost of fencing = $\mathbb{\purple{\boxed{Rs.2800}}\star}$
