Base = 12÷2
= 6
slant height = a
a^2 = 6^2 + 8^2
a^2 = 100
a = 10 cm
Note: The height of the room must be 3 m instead of 3 cm because 3 cm is too small and it cannot be the height of a room.
Given:
Perimeter of the floor of a room = 18 metre
Height of the room = 3 metre
To find:
The area of 4 walls of the room.
Solution:
We know that, the area of 4 walls of the room is the curved surface area of the cuboid room.
The curved surface area of the cuboid is

Where, h is height, l is length and b is breadth.
Perimeter of the rectangular base is 2(l+b). So,

Putting the given values, we get


Therefore, the area of 4 walls of the room is 54 sq. metres.
Answer:
1+2+3- -9+236359
Step-by-step explanation:
<h2>Greetings!</h2><h3>A way to do this is to divide the actual amount by the predicted amount:</h3>
8206 ÷ 13,426 = 0.6112
<h3>To change this back into a percentage simply multiply by 100:</h3>
0.6112 x 100 = 61.1
<h3>So the percent of voter turn out was 61.1%</h3><h2>Hope this helps!</h2>
