Question

Find the cost of painting a wall of length 6m and breadth 5m at the rate of ₹ 120 per sq. m.​

Answer 1

Answer:

length=6m

breadth=5m

area of the wall=lb=6x5=30 sq.m

cost of painting a sq m = 120

so cost of painting 30 sq m= 120x30=3600

Given :

• Length = 6m

• Breadth = 5m

• Rate = ₹ 120 per sq.m

To Find :

• cost of painting a wall of length 6m and breadth 5m at the rate of ₹ 120 per sq. m.

Solution :

Area of wall = Length × breadth

Length = 6m, Breadth = 5m

= 5 × 6 sq.m

= 30 sq.m

Therefore, painting the wall = area × cost per square unit.

Given, rate = ₹ 120 per sq.m

= 30 × 120

= ₹ 3,600

∴ the cost of painting a wall of length 6m and breadth 5m at the rate of ₹ 120 per sq.m is

Explaination.

• In the given question, length is 6 m and breadth is 5m at the rate of ruoees 120 per sq.m. And question is saying to find the cost of painting a wall of length 6m and breadth 5m at the rate of ₹ 120 per sq. m.

• So we will use the formula for Area of wall, so the area of wall is length × breadth, length is 6m and breadth is 5m so we'll multiply them and we will get rupees 30 sq.m

• Second thing is to find the cost of painting, for finding the cost we will use the formula area × cost per square unit. so we'll multiply 30 × 120 and we'll get rupees 3,600.

And we're done!
