What is semi perimeter?
Semi perimeter is given by half of the perimeter value.
What is the semi perimeter of the square with the each side measuring 5 feet.
First we will find the perimeter of square
We know that formula for perimeter of square =4a
Calculate the perimeter =4*5 feet
Now we find the semi perimeter
Semi perimeter = 20/2
Therefore semi perimeter of the given square is 10 feet
What is the semi perimeter of following rectangle length is 9 feet and width is 7 feet.
First we will find the perimeter of the rectangle
We know that formula for finding the perimeter of rectangle is =2(l+w)
Substitute the length and width in the formula we get
Now we calculate the semi perimeter
Semi perimeter =32/2
Therefore the semi perimeter of given rectangle is 16 feet.
Calculate the semi perimeter of following triangle side of the triangle is 12 ,15 ,11
First we will find the perimeter of triangle
Already we know that formula for find the perimeter of triangle is P= a+b+c
Substitute the sides’ value into the formula
Now we will find the semi perimeter
Semi perimeter =38/2
Therefore the semi perimeter of given triangle is 19
