Intro to Area: Video & Questions

Which statement is FALSE?

• Area measures the amount of space inside a 2D shape.

• Perimeter measures the distance around a 2D shape.

• Area is always measured in square units.

• Area is always measured in cubic units.

What is the formula to find the area of a rectangle?

• Length plus width

• Length minus width

• Length times width

• Length divided by width

What does perpendicular mean?

• lines that meet at a right angle

• lines that are parallel

• an acute angle

• congruent, or equal

How do you find the area of a parallelogram?

• Base divided by height

• Base times height

• Base minus height

• Base plus height

• you can actually use any formula for a triangle

• because the base is always half the size of the height

• because a triangle is half of a parallelogram

• V = lwh

• A = lw
