Question

length of rectangle is 7 cm more than its breadth perimeter is 54 CM then what is the length and breadth of the rectangle​

Answer 1

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

Answer 2

Answer:

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
