Question

the length of rectangle is three times its if the breadth of a rectangle is cm4 then find its perimeter
​

Answer 1

Breadth = 4 cm

Length = 3 × Breadth

= 12 cm

Perimeter = 2 ( l+b )

= 2 ( 12 + 4 )

= 2 ( 16 )

= 32 cm

Answer 2

Answer:

32 cm

Step-by-step explanation:

b = 4 cm

l = 3b = 3 x 4 = 12 cm

perimeter = 2(l + b) cm

                 = 2(4 + 12)

                 = 2 x 16

                 = 32 cm
