This is your answer

I hope it it help

Answer 2

Before, finding the answer. Let's find out on how we can find the answer.

• First, we must find the area of the rectangle.

$\sf \: area \: of \: rectangle = l \times b$

• Next, We should multiply the area of rectanglular room with rate of fencing to find the cost of fencing.
• To find the cost of carpet, we must convert to cms and multiply.

Given :

• Length and breadth = 5 m
• Rate for Fencing = Rs. 75
• Rate of Carpeting = Rs. 86.75

To find :

• Cost of Fencing and Carpeting

Solution :

$\sf \: area \: of \: rectangle = l \times b$

$\sf \: area = 5 \times 5 \: sq.units$

$\sf \: = 25 \: m$

Hence, the area of the Rectangle is 25 sq.m

Rate of Fencing = 25 × 75

= Rs. 1875

Since, we are said to find per sq.cm. We have to convert it to cm.

25 m = ? cm

= 25 × 100

= 2500 cms

Rate of Carpeting = 2500 × 86.75

= Rs. 2,16,875.

Final Answer =

Cost of Fencing = Rs. 1875

Cost of Carpeting = Rs. 2,16,875
