Answer:

length \:  =  \: 12 \: cm \\ bredth = 4  \: cm

Step-by-step explanation:

length \: of \: rectangle \:  =  \: 3x \\ breadth \: of \: rectangle \:  =  \: x \\ perimeter \: of \: rectangle = 32 \: cm \\ = >  2(l + b) = 32 \\  = >  2(3x + x) = 32 \\  = > 4x =  \frac{32}{2}  \\  =  > x =  \frac{16}{4}  \\  =  >  x = 4 \\ length = 3x = 3 \times 4 = 12 \: cm \\ breadth = x = 4 \: cm

HOPE IT HELPS!!!

Given:

  • Lenght of a rectangle is 3 times its breadth .
  • Perimeter 32 cm

To find:

  • Find the length and breadth

Soluton:

  • According to question,
  • Lenght of a rectangle is 3 times its breadth
  • So , let

 \sf \: breadth \: of \: rectangle = x \\  \sf \: lenth \: of \: rectangle = 3x

  • We know that,
  • Perimeter of rectangle = 2(length+breadth)

  \sf\implies2(3x + x) = 32cm \\   \implies8x = 32cm \\  \implies \: x =  \frac{32}{8}  \\ x = 4

So \: The, \\  \sf \: Breadth \: = x = 4cm \\  \sf  \: Length = 3x = 3(4)  \\  = 12cm
