Answer:

Let ,breadth be x

length=x+6,

perimeter=2(l+b)=84

l+b=42

x+x+6=42

2x=42-6

2×=36

×=36/2

×=18

length=24

breadth=18

area=24×18=432

Answer:

ATQ If Breadth is = x cm

Then Length is = 2x+6 cm

ATQ Perimeter is = 90 cm

2 [ l+ b] = 90 cm

2[ 2x+6+x] = 90 cm

2[ 3x+6] = 90 cm

6x+12 = 90 cm

6x = 90-12

6x = 78

x = 78/6

x = 13

Then Breadth = 13

And Length = 2 * 13+6= 32
