Plz mark me as a brainllist

Step-by-step explanation:the perimeter of triangle=2 (l+b)=30

(l+b)=30/2=15........eq(1)

breadth is 3 cm less than the length

l=b+3.....eq (2)

From eq (1),

l+b=15 ( Substitute l value in eq (1) we get )

b+3+b=15

2b+3=15

2b=15-3

2b=12

b=12/2=6

breadth value is 63cm

length=breadth+3=6+3=9
