Question

Find the area of right triangle whose base is 1.2cm and hypotenuse is 3.7cm

Answer 1

Hi friend ✋✋✋✋
---------------
Your answer
---------------------

Measure of base of a right triangle = 1.2 cm

Measure of hypotenuse of the right triangle = 3.7 cm

Then,
---------

By Pythagoras theorem
------------------------------------

Measure of is height = 3.5 cm
$height \: = \sqrt{(3.7) {}^{2} - \: (1.2) {}^{2} } \\ \\ = > \sqrt{13.69 \: - 1.44} \\ \\ = > \sqrt{12.25} \\ \\ = > 3.5 \: cm$
Then,
----------

Area of the triangle = 1/2 × base × height

= [1/2 × 1.2 × 3.5] cm²

= 2.1 cm²
