Question

the area of a triangle is 90 centimetres base is 15 cm find its altitude
area of a triangle=90cm

base=15cm
altitude=x
area =1/2×base×altitude
90×2=15x×1
x=180/15
x=12cm​

Answer 1

12cm is the altitude

Answer 2

Area Of Triangle=90 cm²

Base=15 cm

We Know That Area of Triangle

$\frac{1}{2}\times\:Base\:\times\:Altitude$

$\frac{1}{2}\times\:15\times\:Altitude=90$

Altitude=90×2/15


=$Altitude=6\times2$

=Altitude=12 cm

$\boxed{\mathtt{Altitude=12\:cm}}$
