The equation is
Step-by-step explanation:
Let us revise how to make a variable subject of an equation
- Write the equation and circle the variable you want to make it subject
- Keep it in one side and move all other in the other side
- Make the coefficient of the subject 1
∵ A = × b × h
∵ b is the subject
∴ Multiply the two sides by 2
∴ 2A = b × h
- Divide both sides by h
∴
- Switch the two sides
∴
The equation is

Only three regular polygons tessellate<span>: equilateral triangles, squares, and </span>regular<span>hexagons. </span>No<span> other </span>regular polygon can tessellate<span> because of the angles of the corners of the </span>polygons<span>. ... For </span>regular polygons<span>, that means that the angle of the corners of the </span>polygon<span> has to divide 360 degrees</span>
100 - a = 64
