WEEK SEVEN

TOPIC: AREA OF RIGHT ANGLED TRIANGLE

A right-angled triangle has 3 – sides

Area of triangle = ½ x base x height

                         = ½ x 12cm  x 13cm

                                      1            1

                         = 1 x 6cm x 13cm =  78cm²

EXERCISE

Calculate the area of the triangles with the following dimensions

1. Base = 14cm, height = 16cm
2. Base = 10cm, height = 8cm
3. Base = 25cm, height = 22cm
4. Base = 30cm, height = 15cm
5. Base = 24cm, height = 18cm
6. Base = 14cm, height = 16cm
7. Base = 34cm, height = 15cm
8. Base = 52cm, height = 48cm
