ABCD is a rectangle.
Given in cm:
AB = 7
BC = 5
Calculate the area of the rectangle.
Let's calculate the area of the rectangle by multiplying the length by the width:
35
Look at the rectangle below.
Side AB is 2 cm long and side BC has a length of 7 cm.
What is the perimeter of the rectangle?
Area measures the space inside a shape. Think of it like counting squares - if you have 7 squares across and 5 squares down, you need 7 × 5 = 35 total squares. Adding gives you perimeter (distance around), not area!
No! Multiplication works both ways: 7 × 5 = 5 × 7 = 35. Whether you say AB is length or width doesn't change the area calculation.
Since the sides are in centimeters (cm), the area is in square centimeters (cm²). Always square the original units for area problems!
Picture a grid that's 7 squares wide and 5 squares tall. Count all the squares inside - that's your area! You can count them one by one or multiply 7 × 5 for the same result.
For rectangles, always use Area = length × width. If you need the distance around the outside instead, that's perimeter = 2(length + width). Read the question carefully!
