Question

Length of rectangular p ground is twice of its width find dimensiins when perimeter is 30

Answer 1

Heya !!!

Here is your answer.

Given :

Length of a rectangle is double the width and perimeter= 30 units
Let the length be l and breadth be b.

So, l = 2b
Using
P = 2(l+b)
30 = 2 (2b +b)
15 = 3b
b = 5 units.

And l= 2b = 10 units.


Hope You Got IT

Answer 2

Hey dear !!!


Let the width of Rectangular ground be X m.


Length of Rectangular ground = 2X m



According to question,




Perimeter of Rectangular ground = 30


2 ( L + B) = 30



2X + X = 30/2



3X = 15


X = 15/3



X =5 m


Breadth of Rectangular ground = X = 5 m

and,

Length of Rectangular ground = 2X = 2 × 5 = 10 m


Hence,


Dimensions of Rectangular ground is 5 and 10 m.
