Question

Calculate the perimeter of a triangles whose areas is
and 96cm²
whose two sides are 12 cm and 16 cm.​

Answer 1

Step-by-step explanation:

perimeter of Triangle = S

Answer 2

area = 1/2×b×h

= 1/2× 16×h= 96

h= 12

using pythagoras ....

12²+ 16² = (3rd side)²

144+ 256= (3rd side)²

3rd side = 20 cm

...

so perimeter = 16+12+20

= 48 cm
