Question

Find the area find the area of a right triangle whose hypotenuse is 13 cm and one side is 5cm

Answer 1

prependicular)^2 = (hypotenous)^2 - (base)^2
(p)^2 = (13)^2 - (5)^2
p^2 = 169-25
p^2 = 144
p = 12cm

area of right angle traingle = 1/2 × base × height 
= 1/2 × 5 × 12
= 30cm^2

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
