Question

10. The perimeter of a rectangle is 40 1 point cm. The ratio of its sides is 2: 3. Find its length and breadth. * O I = 10 cm, b = 8 cm = O I = 12 cm, b = 18 cm O b m | = 12 m, b = 8 m 0 1 = 40 m, b= 30 m​

Answer 1

Answer:

Length = 12cm, breadth = 8cm

Step-by-step explanation

perimeter = 40 cm

Ratio of length and breadth = 2:3

        P = 2L + 2b

        P = (2*2x) + (2*3x) = 40cm

        P = 4x + 6x = 40cm

        P = 10x = 40cm

        P = x = 40/10 =

        X = 4.0cm

        breadth = 2*4 = 8cm

        length = 3*4 = 12cm

Answer 2

Answer:

Your length will be 12 cm and breadth will be 8 cm .
