WALT find the area of parallelograms.

Maths lesson part 1

What is a parallelogram?

A parallelogram is a 4-sided shape (quadrilateral ) formed by two pairs of parallel lines.

Opposite sides are equal in length and opposite angles are equal in measure.

This means that we can work out the area of a parallelogram in the same way as a rectangle:

we write the formula like this:

Area = Base x Height

A = B x H

Make sure to use the perpendicular height (at a right-angle to the base) rather than the slant height!

Look at the parallelogram below, it looks like a wonky rectangle. The height must be the perpendicular height( at a right angle), measured across the shape.

If we use the the formula, Area = base x height, what is the area of parallelogram?

Click the star to find out the answer.

Were you correct?

Now try finding the area of these parallelograms.

REMEMBER Area= base x height!    Maths lesson part 2
• Today I would like everyone to watch the video and follow the instructions and activities. The video will take you through the activities step by step.

• Pause the video so you can give yourself enough time to work out each question.

• You will need to worksheet with you when you watch the video because you will answer some of the questions as you go.

Remember perpendicular is when lines meet at a right angle.

• Complete all questions
