Question

how to find length of rectangle

Answer 1

if you have the bredth and area then you can find it by the formula l×b

Answer 2

☆Hello friend☆

There are many conditions where length is unknown,

For example :- If b is 50 and perimter is 200, find length.

Perimter = 2( l + b )
200 = 2 ( l + 50 )

200/2 = l + 50

100 - 50 = l

50 = l

OR

if b is 15 and area is 60 find the length

A = l × b

60 = l × 15

60/15 = l , length = 4

Hope it helps☺!
