Question

if the perimeter of a rectangle is 16 and its breadth is 2cm find its length.

Please solve step by step​

Answer 1

perimeter of rectangle= 2 (l+b)
16 =2 (l+2)
16= 4l
16÷4=l
l=4

Answer 2

here is ur answer:

perimeter of a rectangle = 16 cm

breadth = 2cm

length = l

$perimeter \: of \: a \: rectangle = 2(l + b) \\ \\ 16 = 2(2 + l) \\ \\ \frac{16}{2} = 2 + l \\ \\ 2 + l = 8 \\ \\ l = 8 - 2 \\ \\ l = 6 \: cm$

hope it helps you!
