The base and hypotenuse of a right triangle are 5cm and 13cm long.find the area​

Answer»

Answer:

30cm^2

Step-by-step EXPLANATION:

By phythagoras theorem

5^2 + x^2 =13^2

on SOLVING , remaining side =12cm

applying Heron's formula.

area = √{s(s-a)(s-b)(s-c)}

s=(5+12+13)/2=15

so area=√15*10*3*2

=√3*5*5*2*3*2

=√3*3*5*5*2*2

=3*5*2

=30cm^2
