Question

length of rectangular plot is thrice its breath the area of the plot 768m square. find the perimeter of plot.

Answer 1

Answer:

Step-by-step explanation:

L=3b

B=b

P=768m

Now

Acc to que

P= 2(l+b)

768=2(3b+b)

768=2×4b

768/8=b

96m=b

So

B=96m

And

L=3×96

L=288m

Answer 2

Answer:

Step-by-step explanation:

Let, the breadth be x.

So, length would be 3x.

Area = l*b

=> 768 = 3x*x

=> 768 = 3x²

=> 768/3 = x²

=> 256 = x²

=> 16 = x

Length = 3x = 3*16 = 48

Breadth = x = 16

Perimeter = 2(l+b)

=> 2(48+16)

=> 2(64)

=> 128 m
