Question

The area of rectangular piece of cardboard is 54m and its length is 9m. What is the width of the cardboard? Also find the cost of painting it at the rate of Rs 2/m​

Answer 1

Answer:

Area = Length × Breadth

Given Length: 9 m

Given Area: 54 m²

Hence Breadth is calculated as:

⇒ Breadth = Area / Length

⇒ Breadth = 54 m² / 9 m

⇒ Breadth = 6 m

Hence the Breadth of the rectangle is 6 m.

Cost of painting = Cost per m² × Area

⇒ Cost = Rs. 2 × 54

⇒ Cost = Rs. 108

Hence the cost of the painting is Rs. 108.
