Question

the area of a right angled triangle , whose base is 3 cm , is 6 cm². find the other two sides of the right triangle​

Answer 1

Step-by-step explanation:

$area \: \: of \: \: right \: \: triangle \: \: = \frac{1}{2} \times b \times h$

$6= \frac{1}{2} \times 3 \times h$

$6 \times 2 = 3h$

$12 = 3h$

$h = 4cm$

By Pythagoras Theorem,

${a}^{2} + {b}^{2} = {c}^{2}$

${3}^{2} + {b}^{2} = {4}^{2}$

$9 + {b}^{2} = 16$

${b}^{2} = 16 - 9$

${b}^{2} = 7$

$b = 7cm$
