Question

the parimeter of the rectangle is 40 cm. the lenth of the rectangle is more than double its breadth by 2 . find lenth and breadth​

Answer 1

Step-by-step explanation:

perimeter of rectangle=40

length=2b

breadth=b

perimeter of rectangle=2(l+b)

=2(2b+b)

40= 2(3b)

40=6b

b=40/6

b=6.6cm

l=13.2cm

Answer 2

Answer:

Thus length = 2x+2 = 2×6+2 = 12+2 = 14

breadth = x =6

Step-by-step explanation:

Perimeter of the rectangle = 2l+2b

let the breadth = x

then length =2x+2

Perimeter of the rectangle = 40

40=(x+2x+2)×2

40=(3x+2)×2

40=3x×2+2×2

40=6x+4

6x+4=40

6x=40-4

6x=36

x=36÷6

x=6

Thus length = 2x+2 = 2×6+2 = 12+2 = 14

breadth = x =6
