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
