Question

The sides of a right triangle are 5cm, 12 cm and 13 cm. Then its area is
a) 0.003 m square
b) 0.0024 m square
c) 0.0026 m square
d) 0.0015 m square​

Answer 1

Answer:

Given side of triangle is 5 cm , 12 cm and 13 cm

We know that area of triangle=

s(s−a)(s−b)(s−c)

where $$s=\frac{a+b+c}{2} and a, b, c are three sides

s=

2

5+12+13

=15

Then area of triangle=

15(15−5)(15−12)(15−13)

=

15×10×3×2

=

900

=30cm

=0.003m
