**My name is Jack and I am 11 years old. My dad asked me to help him with his maths homework, so I thought it would be a good idea if we did some problems together on the whiteboard in my room. The first problem was this: What is the area of this rectangle? Well, I didn’t really know how to start that one off because there were no numbers or equations written down anywhere! It seemed like a pretty hard question at first but then I realised that you could just cut up the shape into two rectangles and add their areas together! In order to do that though you need all of your measurements straight away. All we knew about our rectangle was its height which was 4 cm and its width which was 2 cm**

**This rectangle has an area of (5.00) square units, which is illustrated by the blue shaded region in the picture above. The length of its base is given by (\frac{1}{2}) times the height, and this gives us a relationship between the lengths of these two sides that can be written as (\frac{\sqrt{3}}{2}), where (\sqrt{3}=1.73205080756888…) .**

**This blog post is about the area of a rectangle. The length is 20cm and the width is 10 cm. To find out what the area is, you multiply these two numbers together. It turns out that it’s 200cm squared.**

**This rectangle has an area of 198.5cm squared. The width is 100cm and the length is 50cm. This means that this rectangle has a total area of 9850 square units, which makes it one of the largest rectangles in the set!**

**The area of a rectangle is the amount of space within its borders. To find the area, multiply the width by the height. The formula for finding an unknown side length in a rectangular equation is [latex]a=lwh[/latex]. [1] For example, if you wanted to find out how much space there was in a standard sheet of paper (8 and 1/2″ x 11″), you would solve 8.5 inches times 11 inches: 87.5 square inches.[2][3]**

**The area of the rectangle is 15. The length is 8cm and the width is 4cm. This can be worked out by multiplying each side by itself, giving an answer of 32 for the length multiplied by width then divided by 2 to give 16 as the final answer.**
