Answer:
Step-by-step explanation:
let the breadth = x
length=x+7
perimeter=54cm
we know that,
perimeter=2(l+b)
54=2(x+x+7)
2x+7=27
2x=20
x=10cm
so breadth=10cm and length=17cm

Step-by-step explanation:
2(x + 7 +x ) = 54 (since length is 7 more tha bredth consider b= x , l = 7+x )
2(2x + 7 ) =54
2x +7 =27
2x = 20
X=10
L= 17
B=10
