What is Wide?
Grade Level:

Definition
What is it?
Wide describes how much something stretches from one side to the other. It tells us the distance across an object, usually its shortest side. A wider object covers more space horizontally.
Simple Example
Quick Example
Imagine you have two different parathas. One is a small, round puri, and the other is a large, flat aloo paratha. The aloo paratha is much wider than the puri because it covers more space across its diameter.
Worked Example
Step-by-Step
Let's find out which road is wider.
Step 1: Measure the width of Road A. Use a measuring tape to find the distance from one edge to the other. Let's say Road A is 10 meters wide.
---Step 2: Measure the width of Road B. Again, use a measuring tape to find the distance from one edge to the other. Let's say Road B is 15 meters wide.
---Step 3: Compare the measurements. Road A is 10 meters wide, and Road B is 15 meters wide.
---Step 4: Determine which is wider. Since 15 meters is greater than 10 meters, Road B is wider than Road A.
Answer: Road B is wider.
Why It Matters
Understanding 'wide' is crucial in Physics for designing structures and in Engineering for building roads or bridges. Architects use it to plan rooms, and city planners use it to design wide, safe streets. It helps engineers make sure things fit or are strong enough.
Common Mistakes
MISTAKE: Confusing 'wide' with 'long' or 'tall'. | CORRECTION: 'Wide' refers to the side-to-side measurement, 'long' is end-to-end, and 'tall' is bottom-to-top.
MISTAKE: Assuming wider means bigger in all directions. | CORRECTION: An object can be very wide but not very long or tall. 'Wide' only describes one specific dimension.
MISTAKE: Not having a consistent reference point when comparing widths. | CORRECTION: Always measure from the true edge of one side to the true edge of the opposite side to get an accurate width.
Practice Questions
Try It Yourself
QUESTION: A cricket pitch is 3.05 meters wide. A football goal is 7.32 meters wide. Which one is wider? | ANSWER: The football goal is wider.
QUESTION: Your school gate is 4 meters wide. Your friend's cycle rickshaw is 1.5 meters wide. How much wider is the school gate than the cycle rickshaw? | ANSWER: 2.5 meters wider.
QUESTION: A highway has two lanes, each 3.5 meters wide. If a divider between them is 1 meter wide, what is the total width of the highway including both lanes and the divider? | ANSWER: 8 meters (3.5 + 3.5 + 1 = 8)
MCQ
Quick Quiz
Which of these objects is typically described as 'wide' in comparison to its height?
A tall, narrow building
A long, thin pencil
A flat, open playground
A very deep well
The Correct Answer Is:
C
A flat, open playground typically has a much greater side-to-side measurement (width) compared to its height. The other options describe objects that are tall, long, or deep, not primarily wide.
Real World Connection
In the Real World
When new metro lines are built in cities like Delhi or Mumbai, engineers must decide how wide the tracks and platforms need to be. They consider the width of trains, the space for passengers, and safety clearances to ensure efficient and safe transport for millions of people daily.

Key Terms
WIDTH: The measurement from one side to the other | DIMENSION: A measurable extent of some kind, such as length, breadth, or height | HORIZONTAL: Parallel to the ground or to the horizon | MEASUREMENT: The process of finding a number that indicates the extent of a quantity
