Answer 1

Answer:

$let \: length \: be \: 3x\\ breadth \: be \: x \\ so \: perimeter \: of \: rectangle = 2(l +b) \\ 56 = 2(4x) \\ x = 7 \\ length = 21cm \\ breadth = 7cm$

Answer 2

Answer:

x = √56/3.

Step-by-step explanation:

breath of the rectangle is x

length of the rectangle is 3x

3x × x = 56cm

3x = √56 cm

x = √56/3.
