cm.
a) 12 b) 13 c) 14. d) 15​

Answer 1

Answer:

perimeter=2×l+b

52=2×l+15

52=30+l

52-30=l

22=l

Answer 2

Answer:

Length of rectangle is c)14cm

Step-by-step explanation:

Breath = 12cm

Length = ?

Perimeter = 52cm

                 = 2 (l +b)

                 = 2 x (l + 12)

                 = 2l + 24

  2l = 52 - 24

      = 28

l = 28/2 = 14cm
