the lenghtvof each side of a square is 2.5 meter. if each side is doubled in length, what is the effect on the perimeter of the square? a.it remain the same b.it is one half the original perimeter c. it is four time the original perimeter d. it is twice the original perimeter.

T=4.5


Simplifying 3t + 4 = t + 13
Reorder the terms: 4 + 3t = t + 13
Reorder the terms: 4 + 3t = 13 + t
Solving 4 + 3t = 13 + t
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-1t' to each side of the equation. 4 + 3t + -1t = 13 + t + -1t
Combine like terms: 3t + -1t = 2t 4 + 2t = 13 + t + -1t
Combine like terms: t + -1t = 0 4 + 2t = 13 + 0 4 + 2t = 13
Add '-4' to each side of the equation. 4 + -4 + 2t = 13 + -4
Combine like terms: 4 + -4 = 0 0 + 2t = 13 + -4 2t = 13 + -4
Combine like terms: 13 + -4 = 9 2t = 9
Divide each side by '2'. t = 4.5
Simplifying t = 4.5


I got help from a website called geteasysolution

Answer:

Step-by-step explanation:

Alright, lets get started.

The side length of square is given as 2.5.

So, the perimeter if square will be : [tex]4*2.5=10.0[/tex]

Once the side is doubled, means new dimension of side of square will be : [tex]2*2.5=5[/tex]

So the new perimeter will be : [tex]4*5=20[/tex]

The original perimeter is 10.

The new perimeter is 20.

It means the perimeter is twice the original perimeter.   :   Answer D

Hope it will help :)
