I'm guessing you're asking what shape do you get if you cut a hexagon is cut into sixths.
If this hexagon is a regular hexagon, then the shapes would be equilateral triangles.
Answer:
97.27 yd²
Step-by-step explanation:
First let's find the area of the right triangle on the left side. To do that, multiply 6x5, then divide the product by 2, since a right triangle is half a rectangle.
6x5=30
30/2=15
Area of triangle=15 yd²
Find area of the middle rectangle. So multiply the length by the width.
9x6=54
Area of rectangle=54 yd²
Find area of the half circle. Formula for area of circle is
. Pi is about 3.14, and radius (
) is 3. Radius is half of the diameter of circle, and the 6 on the left says the diameter of circle.
x
≈28.27
Area of circle is about 28.27 yd²
Add up the three areas.
15+54+28.27=97.27
The word that describes it is congruent
