Good morning everyone! Hope you are all OK?
Well done for yesterdays maths work, I loved seeing all of your pictures!
Sorry for the late post, my internet hasn’t been working very well.
Today we are going to be looking at perimeter of squares and rectangles.
Perimeter means the length of the outside of the shape. Imagine a fence that goes around the outside of your garden, the total length of the fence is the perimeter.
We are looking at squares and rectangles today. We know that a square has 4 sides which are all the same length and a rectangle has 4 sides where 2 sides that are opposite or parallel to each other are the same. We can use this information to help us calculate the perimeter.
Use the squares to help you calculate the length of each side (remember 1 square = 1cm) or if you have printed the sheet and have a ruler you can measure it.
Add the 4 side lengths together to calculate the perimeter.
A square has 4 sides which are 5cm long
we need to add the 4 sides up :
5cm + 5cm +5cm +5cm = 20cm or 5cm x 4 = 20cm
Your perimeter is 20cm.
A rectangle has 2 sides which equal 3cm and 2 sides which equal 6cm
We need to add the lengths of all 4 sides together:
3cm + 3cm +6cm +6cm = 18cm
The perimeter is 18cm.
Please complete the questions below and write your answers in the comments. The blue link will bring a clearer sheet up.
