Question

The length of a rectange is twice its breadth if its perimeter is 60 cm then find the length and breadth of rectangle​

Answer 1

Step-by-step explanation:

pri. of tri.=L×B

60cm=2B×B

60cm =3B

60/3cm=B

20cm=B

40cm=L

Please marked me as brainiest.

Answer 2

Let L be the length.

Then L = 2B or B = L/2

Perimeter of Rectangle = 2 (L + B)

or,

2 (L + L/2) = 60 cm

6L/2 = 60

L = 20 cm

B = L / 2 = 10 cm
