Step-by-step explanation:
Don't take my word for it
Given :
Area of rectangle.
To Find :
The dimensions of a rectangle (in m) with area 1,728 m2 whose perimeter is as small as possible.
Solution :
Let, the dimensions of rectangle is x and y.
Area, A = xy.
x = A/y. ....1)
Perimeter, P = 2( x + y )
Putting value of x in above equation, we get :

For minimum P,

SO, it is a square.

Therefore, the dimensions are
.24\sqrt{3}
Hence, this is the required solution.
All angles are the same and all side lengths are equal/congruent
If the legs are legnth x, then the hyptonuse is x√2
x√2=7
divide both sides by √2
x=7/√2
times (√2)/(√2)
(7√2)/2
