Area and Perimeter of Rect, Tri and Trap Practice Test

Define Perimeter

• The distance around the outside of an object

• The space inside of an object

• Base times height

• The sum of the squares of any two sides of a right triangle is equal to the square root of the remaining side

Define Area

• The distance around the outside of a shape

• It's the area

• The space inside of an object (measured in how many squares fit inside)

• $A=\pi r^2$

Why do some diagrams show a dashed line? What does it represent?

• It's the base

• It shows the perimeter of the shape

• The dashed line shows the vertical height which is the height we use to calculate the area.

• The dashed line shows the outer area as opposed to the inner area

How does a triangle relate to a rectangle?

• Triangles are always HALF of a rectangle.

• Triangles are ONE THIRD of a rectangle. That's what "tri" means.

• Triangles relate well to rectangles.

• Triangles and are ONE FIFTH of a rectangle. That's what "Tri" means.
