How-To: Find Area And Perimeter of Circles and Squares in Hopscotch

How to find area of circles and squares

This is pretty easy, but here is a tutorial on finding the area of squares and circles

Squares

Area

The algorithm for finding the area of a square is simple, (AB). It’s the same in Hopscotch. Using values as the A and B, you can find the square’s area in square pixels.

For example, say the square’s width is 90 and it’s height is 130. A is called “Side1” and B is called “Side2” in this tutorial, but you can name it whatever you want, as long as you remember it!

Written Code
When Game Starts

Create A Clone Of This Object
Set Value “Side1” to “Self Size as a Percentage”/“Sides”
Set Value “Side2” to “Self Size as a Percentage”/“Sides”

When Object Is Cloned

Set Position X (Self X Position) Y ([Original Object Y Position] — [(Height) • 1.9]
Repeat Forever
Set Text To (Area)
End

When Game Starts

Set Sides To [4(Insert How Many Sides Here, In This Case 4)]

When 7 = 7

Set Value (Area) to (Side1) • (Side2)

Perimeter

Perimeter of squares is easy, as long as you know how long each side is. The algorithm for this is (A2 + B2)—For squares and rectangles ONLY, quadrilaterals are way different :wink: .

Written Code
When Game Starts

Create A Clone Of This Object
Set Value “Side1” to “Self Size As A Percentage”/“Sides”
Set Value “Side2” to “Self Size As A Percentage”/“Sides”

When Object Is Cloned

Repeat Forever
Set Text To “Perimeter”
End

When 7 = 7

Set Value “Perimeter” to (“Side1” • 2) + (“Side2” • 2)

Picture Code

Simple Way

You just figure out “Side1” and “Side2” values using the “Size Method”

Actual perimeter calculation in real life:
Rectangle/square: Length x Width
Triangle: Base x Height

That’s area

Perimeter is all four sides added

For perimeter, if you use the Distributive Property, you can make it look like this:

That’s simpler, thanks for that:)

This is a great tutorial! I love the way you explained how to find each method, area and perimeter!
