Question

the perimeter of rectangle is 46 cm the breadth of rectangle is 12 cm find its length​

Answer 1

Answer:

11 cm

Step-by-step explanation:

Perimeter of a rectangle (p)= 2(l+b)

or 46 cm=2l+2b

or 46cm= 2l+ 2*12cm

or 46 cm =2l+24cm

or 46 cm -24cm =2l

or 22 cm =2l

or l= 22cm/2

so, l=11 cm

Answer 2

Answer:

Perimeter of Rectangle = 2(Length + Breadth)

⇒ 46 = 2(Length + 15)     

⇒ Length=8 m

d2=L2+B2

Hence, d= 17 m
