Question

the length of a rectangular plot is thrice its breadth the area of the plot 768 metre square find the perimeter of the plot?​

Answer 1

Step-by-step explanation:

let the length be 3x and breadth be x

therefore, area of rectangular plot=l×b sq.units

=768=3x×x

3 x square=768

x square=768/3

x square=256

x= root of 256

x=16 m

therefore,

length=3(16)=48 m

breadth=16 m

now,perimeter of rectangular plot=2(l+b)units

=2(48+16) units

=2(64)

=128 m
