Question

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

Answer 1

✧❥♡⚘✮ʜᴇʏᴀ ᴍᴀᴛᴇ ʜᴇƦᴇ ɪֆ ʏᴏᴜƦ ᴀɴֆᴡᴇƦ :

Let the breath = x

so length = 2x

perimeter of rectangle = 2(l+b)

60 = 2(2x + x )

60 = 2 × 3x

60 = 6x

x = 60/6

x = 10

Hence, length is 2x = 20 cm

Answer 2

Step-by-step explanation:

Let breadth be x.

Length =2x

If perimeter is =60cm

Perimeter =2*(l+b)

60=2*2x+x

60 =2*3x

60/2=3x

30=3x

X=30/3

X=10
