Answer 1

Explanation:

$answer$

According to the question,

= $\sqrt[2]{3 \: \times 3 \: = \: 5}$

= 2 × 3 × 3 = 5

= 6 × 3 = 5

= 18 = 5

= $\frac{18}{5}$

= 3.6

Therefore, the correct answer is 3.6

Answer 2

Answer:

Step-by-step explanation:

SOLUTION

Let the breadth of the room be x meters.

As the length of the room is 50% more than its breadth,

Cost of carpeting the room at the rate of ₹38.50 m² = ₹(3x²/2 × 38.5).

= > x = 4.=>x=4

Hence :

the length of the room = 3/2x meters = 3/2 × 4 meters = 6 meters

and its breadth = x meters = 4 meters.

Let the height of the room be h meters.

Then :

The surface area of all the walls of the room

=> 2(length + breadth) × height

=> 2(6 + 4) × h m²

=> 20h m².

Area of one door = 1 × 2 m² = 2m²,

area of two windows = 2(1 × 1.5) m² = 3m².

Surface area to be prepared

=> surface area of walls - surface area of door and windows

=> (20h - 2 - 3) m²

=> (20h - 5) m².

Cost of preparing the walls of the rate of ₹3.30 m² = ₹(20h - 5) × 3.30.

According to given :

(20h - 5) × 3.30 = 214.50

=> 20h - 5 = 214.50/3.30 = 65

=> 20h = 65 + 5

=> 20h = 70

=> h = 70/20

=> h = 3.5

Hence :

The height of the room = 3.5 meters.
