Let see this points :-

If two or more rectangles have the same dimensions is because they are congruent.

In this way, they share two corresponding sides. Our first rectangle has the following sides:

L1 = x

L2 = 3x + 4

the second and third rectangles need to have the same sides.

Therefore, we will have that the sides of the second one is also:

L1 = x

L2 = 3x + 4

and the sides of the third one is also:

L1 = x

L2 = 3x + 4

Therefore, the total amount of fencing needed is:

T = 3(3x + 4) + 4(x)

T = 9x + 12 + 4x

T = 13x + 12

Moreover, we can compute the area of the fence as follows:

A = [(3x + 4) + (3x + 4) + (3x + 4)]x = (3x + 3x + 3x + 4 + 4 + 4)x

A = (9x + 12)x

A = 9x² + 12x
