Question 0

How do you find the area of a rectangle?

Answer 0

To find the area of a rectangle you multiply the length by the width ( L ✖️ W )

Question 1

What is the area of any shape?

Answer 1

The area of any shape is the amount of surface enclosed within its boundary lines.

Question 2

How do you find the area of a triangle?

Answer 2

To find the area of a triangle you multiply half the base by the perpendicular height. ( 1/2b ✖️ H )

Question 3
