Encourage your learners to use suitable units for area throughout this worksheet.

In sections A and B, learners will calculate the area of various non-right angled triangles either on a cm square grid or from given dimensions.

Students are encouraged to find the area of the two rectangles each triangle fits within first and then halving to get the area of each triangle.

Learners are tasked with drawing two different non-right angled triangles with an area of 15 cm² on a cm square grid in section C.

In section D, students will have to measure the correct length of a triangle in order to calculate its area.

Section E, is made up of three different problems including finding the area of a compound shape.
