Question

If breadth and perimeter are 12.5 and 101 respectively what is the length of rectangle

Answer 1

Answer:

formula to find length

p-2 b/2

(101-25)/2

76/2

38

Answer 2

Perimeter = 2*[l+b] = 101 cm

breadth = 12.5 cm

length is

             2*[l+b] = 101

              2*[l+12.5] = 101

              2l + 25 = 101

              2l = 101 - 25

              2l = 76

              l = 76/2

              l = 38

therefore length is 38 cm
