Question

The cost of plastering a square wall at the rate of Rs.14 per sq. m. is Rs.1694.find the length of each side of the wall.

Answer 1

Answer:

11 m

Step-by-step explanation:

Cost = Area × Rate

        Therefore,

⇒ 1694 = area × 14

⇒ 1694/14 = area

⇒ 121 = area

Let the side length of the square wall be x. So, area of wall is side² = x².

⇒ 121 = x²

⇒ √121 = x

⇒ 11 = x

Length of each side of the wall is 11 m

Answer 2

Given :-

Total rupees = 1694

rate of Rs.14 per sq. m

To Find :-

Length of side

Solution :-

At first we need to find area

1694 = Area × 14

1694 = 14Area

1694/14 = Area

$\sf Area = 121 m$

Now

Side = √Area

Side = √121

Side = 11 m
