Area of Basic Shapes

Area of a Square or Rectangle:

Formula: Area = Length x Width
Example:
Length = 20'
Width = 10'
Area = 10 x 20
Area = 200 sq. ft.

Area of a Right Triangle

Formula: Area = 1/2 (base x height)
Example:
Base= 10'
Height = 10"
Area= 1/2 x (10 x 10)
Area = 50 sq. ft.

Area of a Circle:

Formula: Area = π r² (pi x radius squared)
Example:
π= 3.141
r = 10'

Area= 3.141 x 10 x 10
Area = 314.1 sq. ft.

Area of an Irregular Shape

Area

Section the irregular area into basic shapes. Calculate the area of each basic shape and add the areas for each together.
Example:
Rectangle: 50' by 40'
    Area = 50 x 40 = 2,000 sq.ft.
Circle: radius = 41 '
    Area = 3.14 x 41 x 41 = 5,278 sq.ft.
Triangle A = 20' by 20'
     Area = 1/2 x (39 x 5) = 200 sq.ft.
Triangle B = 10' by 39'
     Area = 1/2 x (39 x 5) = 97.5 sq.ft.
Total Area = 7,575.5 sq.ft.

QUESTIONS & ANSWERS

Ask a Question
  • Do these come in black ?

    Hi! These only come in brown.

  • Can you stack these?

    Hi! These aren't meant to be stacked since they are rounded on top.
    We do have a 6'' high border, as well as an 8'' high border if you are looking for a higher option.
    Thanks!

  • How deep of a trench do you need Or should I not put them in the ground and only have the top part showing? I have 4 inches of rubber mulch to put inside the playground

    Hi! You don't need to dig a trench, just secure the borders to the ground using the stakes that they come with, and then fill the area with rubber mulch!
    Thanks
