Question

Q. What will be the perimeter of the following rectangles? (a) Length = 12 cm. Breadth = 4 cm.Perimeter = 2​

Answer 1

Answer:

given

   length(l)=12cm

   breadth(b) = l - 4

                 = 12-4

                 = 8cm

 perimeter = 2*(l + b)

                    = 2* (12 + 8)

                    = 2* 20

                  =40cm

Answer 2

Answer:

perimeter of rectangle= 2(l+b)

= L: 12cm , B: 4cm

= 2(12+4cm)

2×16cm

=32 cm ans....
