Perimeter?
1 Answer
See a solution process below:
Explanation:
The shape in the problem, from a perimeter point of view can be divided into two parts: a 3 sided "square" and a semi circle.
Three Sided Square
Each side of the three sided square is 9 m therefore the perimeter of this section of the shape is:
Semi-Circle
The formula for the perimeter or circumference of a circle is:
We know the diameter of the semi-circle is 9 m therefore the perimeter of a circle 9 m is:
We now can divide this by 2 to calculate the perimeter of a semi-circle or a half circle:
Total Perimeter
We add the perimeter of the two partial shapes to obtain the perimeter of the complete shape:
The shape has a perimeter of 41.13 m
