Question
The perimeter of the following figure is

- 2P+Q+R
- P-2Q+R
- 2P+2Q+R
- P+2Q+R
Hint:
add the given sides.
The correct answer is: P+2Q+R
Perimeter of the polygon = sum of all its sides.
= (P+Q) +(R-P)+ (2P+Q-R) +(R-P)
= P+Q +R-P + 2P+Q -R +R - P
= P +2Q +R
perimeter is the sum of the sides of a polygon.

Differentiation is the process of determining a function's derivative. The derivative is the rate at which x changes in relation to y when x and y are two variables. A constant function has zero derivatives. For instance, f'(x) = 0 if f(x) = 8. So the derivative function is odd.
