Question

find the area of a right triangle whose base is 1.2 metre and hypotenuse is 3.7 m

Answer 1

Base = 1.2 m

Hypotenuse = 3.7 m

$perpendicular = \sqrt{ {h}^{2} - {b}^{2} } \\ p = \sqrt{ {3.7}^{2} - {1.2}^{2} } \\ p = \sqrt{13.69 - 1.44} \\ p = \sqrt{12.25} \\ p = 3.5$
Perpendicular = 3.5 m


Area = Base *Perpendicular /2

= 1.2 * 3.5 /2

= 0.6 * 3.5

= 2.1 m^2

Answer 2

hey...

to find area of right triangle we need BASE and HEIGHT.

Height can be find out by using pythagores theorem.

area = 2.1 m^2.
