Question

a rectangle has a perimeter of 96cm . its length is twice its breath . find the dimension​

Answer 1

Answer:

Step-by-step explanation:

length=l

breadth=b

so, as in ques. length=2b

perimeter:-

2(l+b)=96

2(2b+b)=96

4b+2b=96

6b=96

b=16cm......

therefore,L=2b

L=2*16

L=32cm

Answer 2

Answer:

Step-by-step explanation:

given that  ...2B = L

and   P=96          ...........(1)

also we know that

P = 2(L+B)            ...........(2)

so using (1) and (2)

2(L+B) =96

2( 2B + B) = 96

2(3B) =96

6B =96

b= 96/6 =16cm

and length is twice the breadth so  

L= 2*16 =32 cm
