Solution

Base = 48 cm 

Hypotenuse 50 cm

First we will find the height of the triangle; let the height be ‘p’. 

⇒ `(Hypotenuse)^2=(base)^2+p^2` 

⇒`50^2=48^2+p^2` 

⇒ `P^2=50^2-48^2` 

⇒`P^2=(50-48) (50+48)` 

⇒`P^2=2xx98` 

⇒`P^2=196`  

⇒`P=14cm` 

Area of the triangle=`1/2xxbasexxheight` 

=`1/2xx48xx14` 

=`336cm^2`
