An equilateral triangle is shown inside a square inside a regular pentagon inside a regular hexagon. Write an expression for the area of the shaded regions.

Respuesta :

Answer:

the shaded area= area of the regular hexagon-the area of the regular pentagon+ the area of the square-the area of the equilateral triangle

Step-by-step explanation:

for the equation to be true we must first identify the shapes used.

the shapes used include  

  • regular hexagon
  • regular pentagon
  • square
  • equilateral triangle

now that we know the shapes we must find out which shapes are shaded

  • regular hexagon (shaded)
  • regular pentagon (not shaded)
  • square (shaded)
  • equilateral triangle (not shaded)

now we know which shapes are shaded we can now form the equation to find the area

i will turn the shapes into varibles so its easier on my brain and yours

  • area of the regular hexagon= h
  • area of the regular pentagon= p
  • area of the square= s
  • area of the equilateral triangle= t
  • shaded area= A

we can know use the info gathered earlier to create the equation

shaded area = (area of the regular hexagon - area of the regular pentagon (the hexagon is shaded while the pentagon is not therefore you would subtract the area of the hexagon by the area of the pentagon))+(area of the square- area of the triangle( same reason as the hexagon and pentagon the triangle is not shaded therefore creating a gap in the square)

or in other words with the variables

A=( h-p )+( s-t )
