Answer 2

To find the area of a right-angled triangle, we can use the formula:

Area = (base * height) / 2

Let's calculate the areas of the given right-angled triangles.

Triangle 1:

The base of the first triangle is 4 cm and the height is 7 cm.

Using the formula, we can calculate the area as follows:

Area = (4 cm * 7 cm) / 2 = 28 cm²

Triangle 2:

The base of the second triangle is 1.2 dm and the height is 25 cm.

First, we need to convert the base from decimeters (dm) to centimeters (cm). Since 1 dm is equal to 10 cm, the base of the second triangle is 1.2 dm * 10 cm/dm = 12 cm.

Using the formula, we can calculate the area as follows:

Area = (12 cm * 25 cm) / 2 = 150 cm²

Therefore, the area of the first right-angled triangle is 28 cm² and the area of the second right-angled triangle is 150 cm².
