Question

give me full solution of question number 5

Answer 1

perimeter of a triangle=2 (l+b)

given,l=b+3

so,2 (b+3+b)=30m

2 (2b+3) = 30m

2b+3 =15m

2b = 12m

so..b = 6m

applying l= 9m and b=6m

Answer 2

Let bredth is x m.
And Length is x+3 m.
so,
the perimeter of rectangle= 30 m
or,2(l+b)=30
or , x+3+x=30/2m
or,. 2x=15-3
so, x=12/2
x=6

therefore breadth=x=6m
and Length=x+3=6+3=9m

I hope it helps you
