In today’s lesson, we will be recapping how to assignment out the breadth of a rectangle, a triangle and a parallelogram.
This assignment includes:
two activities
Created in affiliation with Numerise.
The breadth of a appearance is the bulk of amplitude a appearance takes up. A shape’s breadth is abstinent in aboveboard units, eg aboveboard centimetres (cm²), aboveboard metres (m²) and aboveboard kilometres (km ²).
In the archetype on the right, anniversary aboveboard has a ancillary breadth of 1 cm and an breadth of 1 cm².
There are 2 rows of 4 squares so there are 8 squares in total.
The rectangle has an breadth of 8 cm².
Instead of counting the squares, we could accept begin how abounding centimetre squares were central the rectangle by adding the amplitude by the length.
Area of a rectangle = amplitude × length
Let’s use the blueprint to assignment out the breadth of the rectangle on the right.
Area of a rectangle = amplitude × breadth = 3 × 5 = 15
Remember to accommodate units with you acknowledgment – actuality our ancillary lengths are in centimetres so the breadth is in aboveboard centimetres (cm ²).
The breadth of the rectangle is 15 cm².
Looking at the diagram, if you accumulate the abject by the erect height, you will get the breadth of the abject rectangle.
The breadth of the triangle is absolutely bisected of the breadth of the rectangle. So, to acquisition the breadth of the triangle, accumulate the abject by the erect height, and bisect by two. The blueprint is:
Area of a triangle = (base × height) ÷ 2
Using this blueprint for the triangle aloft we get:
Area of a triangle = (base × height) ÷ 2 = (7 × 4) ÷ 2 = 28 ÷ 2 = 14
Remember to consistently accommodate units with your answer.
The breadth of the triangle is 14 cm².
Calculate the breadth of the triangle.
Area of a triangle = (base × height) ÷ 2 = (5 × 8) ÷ 2 = 40 ÷ 2 = 20
Remember to consistently accommodate units with your answer.
The breadth of the triangle is 20 cm².
A parallelogram is a quadrilateral breadth adverse abandon are both alongside and according in length.
The diagram beneath shows how you can adapt a parallelogram in adjustment to accomplish a rectangle breadth the abject and erect acme break the same.
This agency that we can assignment out the breadth of a parallelogram in the aforementioned way as a rectangle:
Area of a parallelogram = abject × height
Make abiding to use the erect acme (at a right-angle to the base) rather than the camber height!
Area of a parallelogram = abject × acme = 9 × 8 = 72
Remember to consistently accommodate units with your answer.
The breadth of the parallelogram is 72 cm².

Remember: if you apperceive the breadth of a shape, you can assignment out an alien breadth of a ancillary by substituting the breadth and accepted breadth aback into the breadth equation, and isolating the alien value.
