The answer oils be 2 square root 2 because 4 times 2 is 8 and because the square root of 4 is 2 you would move that 2 to the outside and keep the other two on the inside of the square root.

The perimeter of the rectangle is 146 units. What is the length of the longer side?

NeTakaya

we know that

the perimeter of the rectangle is equal to

$P=2W+2L$

where

P is the perimeter of the rectangle

W is the width of the rectangle

L s the length of the rectangle

In this problem

$P=146\ units \\ W=2x\\ L=3x+3$

Substitute the values in the formula above

$P=2W+2L\\ 146=2*(2x)+2*(3x+3)\\ 73=2x+3x+3\\ 5x=70\\ x=14\ units$

$W=2x=2*14=28\ units\\ L=3x+3=3*14+3=45\ units$

therefore

the answer is

the length of the longer side of the rectangle is equal to $45\ units$
