please answer this question fast

Answer 1

Area of rectangle =lb

6912=3x×4x

12x2=6912

X2=6912/12

X2=576

X=24

3x= 3x24=72
4x=4x24=96

Answer 2

let length is 3x and breadth is 4x
area of rectangle = Length x breadth
6912 = 3x×4x
6912 = 12x^2
x^2 = 6912÷12
x^2 = 576
x = 24
so length = 72 cm
and breadth = 96cm
