Given the following rectangle:
Find the area of the rectangle.
Let's calculate the area of the rectangle by multiplying the length by the width:
10
Look at the rectangle below.
Side DC has a length of 1.5 cm and side AD has a length of 9.5 cm.
What is the perimeter of the rectangle?
Area measures how much space is inside the rectangle. When you multiply 2 × 5, you're finding how many unit squares fit: 2 rows of 5 squares each = 10 total squares!
Not at all! Whether you calculate 2 × 5 or 5 × 2, you get the same answer: 10 square units. Multiplication is commutative!
Area is always measured in square units. If your dimensions are in cm, the area is in cm². If in meters, then m². Always remember to square the units!
Picture the rectangle divided into unit squares! You have 2 rows and 5 columns of squares, giving you 2 × 5 = 10 individual squares total.
If you got 7, you probably added the dimensions: 2 + 5 = 7. But that gives you part of the perimeter, not the area! Remember: area needs multiplication.
