The perimeter may not be small enough to measure with just a ruler. For example, if a side of a rectangle was 30 inches, how would you use a 12 inch ruler to accurately measure that side? Also, if you were measuring a shape like a circle or oval, a tape measure is flexible.

Answer:
Price of paint = Rs 16,640
Step-by-step explanation:
As 3 dimensions are given so the third one must be for ceiling.
So in this case, we can find area as follows:
Area = 2(length * width) + 2(length * height)+ 2(height * width)........eq1
Lets say:
Length = 8m
Width = 6m
Height = 4m
So putting value in eq1 we get:
Area = 2(8*6) + 2(8*4) + 2(4*6)
Area = 2(48) + 2(32)+ 2(24)
Area =96 + 64 + 48
Area = 208 sq. m
Now for calculating price:
Price of paint = 208 * 80
Price of paint = Rs 16,640
I hope it will help you!
