Question

sides of the triangle are in ratio of 2:2:1 and its perimeter is 30cm.Find the area of this triangle.​

Answer 1

Answer:

34.86cm square

Step-by-step explanation:

let each side be X cm

2x+2x+X=30

X=6

each side are 12cm,12cm,6cm

area of triangle= √ p ( p − a ) ( p − b ) ( p − c )

where p=side 1+2+3÷3

=15

area = √ 15(15-12)(15-12)(15-6)

=34.86
