Question

The length and width of a carpet are 4m and 3m. respectively. Find it's area. Also, find the cost of the carpet at the rate of Rs 45 per square metre.​

Answer 1

Answer:

Thus, area of carpet = 12 sq. m

Hence, cost of carpet = ₹ 540

Step-by-step explanation:

Given,

Length of carpet , (l) = ₹ 4 m

Width of carpet , (b) = ₹ 3 m

Then, the shape of carpet = rectangular.

Area of rectangle = l × b

So,

Area of carpet = 4 × 3 = 12 sq. m

Thus, area of carpet = 12 sq. m

Now, rate of carpet = ₹ 45 sq. m

Cost of carpet = 12 × 45 = ₹ 540

Hence, cost of carpet = ₹ 540

Answer 2

Answer:

ans:  12 and 540

Step-by-step explanation:

area of carpet=length×width

area of carpet=4×3 m²

∴ area of carpet=12 m²

then,

       rate of 1 m² carpet=Rs 45

       rate of  12 m²carpet=x

            x=45×12=540

    ∴rate of carpet of area 12 m² is Rs 540
