Calculating the area of parallelograms and triangles

A Year 6 maths worksheet, created by an experienced teacher, on calculating the area of parallelograms and triangles.

To work out the area of a triangle, we use the formula: area = ½ x base x height. See if you can calculate the areas of these triangles.

 

How do KS2 children learn to calculate the area of parallelograms and triangles?

In Key Stage 2 (KS2), children learn to calculate the area of parallelograms and triangles by using simple formulas based on what they already know about rectangles. 

Here's how they do it:

• For parallelograms, they multiply the base by the height, just like with rectangles.
• For triangles, they multiply the base by the height, then divide the answer by 2.
• They use visuals like diagrams and shapes to help them understand why the formulas work.

This should build on their existing knowledge of area.

How will this teacher-created worksheet help your KS2 child?

This resource provides clear explanations in a colourful layout that will encourage your child to practise what they know and build their confidence at home and in the classroom. Examples are provided, as well as answers to the activities.
