Question

the sides of a triangle are 3 cm 3 cm and 5 cm find its area​

Answer 1

Answer:

Step-by-step explanation:

S= a+b+c/2

S=3+3+5/2

S=11/2=5.5

Now

By herons formulae of a triangle

Underoot s(s-a)(s-b)(s-c)

Underoot 5.5(5.5-3.0)(5 .5-3.0)(5.5-5)

Now u can solve

Answer 2

base = 3cm

height= 5cm

perpendicular= 3cm

Area of triangle= 1/2 ×b× h

= 1/2×3×5

= 15\2

=7.5cm²
