Question

in a rectangle,L= 3x, b= X and perimeter =48 units.​

Answer 1

Answer:

perimeter of rectangle = 2(l+b)

48 = 2*(3x+x)

48 = 8x

48/8 = x

6= x

3x=3*6  = 18

Step-by-step explanation:

Answer 2

Answer:

Length = 3x

Breadth = x

So, perimeter = 2 ( length + breadth )

So,

2 (3x+x)= 48

2*4 x=48

8x= 48

x= 48/8

x= 6

so, length =3*6

=18 units

And breadth 6 units.

I hope you understand it .
