Anisoscelestriangle has perimeter 30 cm and each of the equal sides is

1.	Anisoscelestriangle has perimeter 30 cm and each of the equal sides is 12 cm. Findthe area of the triangle.
Answer» Let The Third Side Be xcm. Now Perimeter = 12+12+x 24+x = 30 x = 6 Now Find The Area Using Herons Formula Semiperimeter = 30/2 = 15 Sq Root(15(15-12)(15-12)(15-6) ) = Sq Root(1533*9) = Sq Root(1215) = 34.85 cm^2 So Area is 34.85cm^2

Anisoscelestriangle has perimeter 30 cm and each of the equal sides is 12 cm. Findthe area of the triangle.

Answer»

Let The Third Side Be xcm.

Now Perimeter = 12+12+x

24+x = 30

x = 6

Now Find The Area Using Herons Formula

Semiperimeter = 30/2 = 15

Sq Root(15(15-12)(15-12)(15-6) ) = Sq Root(15*3*3*9) = Sq Root(1215) = 34.85 cm^2

So Area is 34.85cm^2
