Answer» Answer: 36 CM Step-by-step explanation: ½ x base x height ( or ½ x b x H ) = 54 =) ½ x b x 12 = 54 =) b x 6 = 54 =) b = 9 We get base to be of 9 cm long. Now, by Pythagoras THEOREM, Hypotenuse2 = Base2 + Height2 = 9 square+ 12 square = 81 + 144 = 225 = 15 square =) Hypotenuse = 15 THEREFORE, perimeter = sum of sides = 9 cm + 12 cm + 15 cm = 36 cm Hope this helps you.

Answer»

Answer:

36 CM

Step-by-step explanation:

½ x base x height ( or ½ x b x H ) = 54

=) ½ x b x 12 = 54

=) b x 6 = 54

=) b = 9

We get base to be of 9 cm long.

Now,

by Pythagoras THEOREM,

Hypotenuse2 = Base2 + Height2

= 9 square+ 12 square

= 81 + 144

= 225

= 15 square

=) Hypotenuse = 15

THEREFORE, perimeter = sum of sides

= 9 cm + 12 cm + 15 cm

= 36 cm

Hope this helps you.
