Question

2. Find the base of a triangle whose area is 0.48 dm2 and altitude 8cm
3.Find the area of a right triangle whose hypotenuse is 13 cm and one side is 5 cm.​

Answer 1

Step-by-step explanation:

This is the answer to your question.

Answer 2

Given:

Hypotenuse = 13cm

One side = 5cm

To Find:

Area

Formula:

The formula to find the area of right angle triangle is 1/2 base x height.

Find:

First we have to find the other side of the triangle.

A/Q Lets find:

5² + x² = 13²

25 + x² = 169

x² = 169 - 25

x² = 144

x = 12

Now we got the other side as 12cm

Solution:

1/2 x 12 x 5

6 x 5

30 cm²
