Question

If one side of triangle is 10 meter and base is 15 meter and area is 80 Sq. meter Find the third side​

Answer 1

$tringle \: area = \frac{1}{2} \times base \times height$

$so \: base \: is \: 15cm$

And we assume that height is x

so equation is,

$80 = \frac{1}{2} \times 15 \times x$

$80 \times 2 = 15x$

$160 = 15x$

$x = \frac{160}{15}$

$x = 10.66cm$
