In this question, the perimeter of this rectangle here is given as 146 units.
00:08
Perimeter of the rectangle is given as 146 units.
00:12
And we have to find the length of the longer side of the rectangle.
00:19
First of all, we know that perimeter of a rectangle is equals to twice of length plus width of the rectangle.
00:31
Here in our question, this distance of 2x units is the length of the rectangle.
00:41
The length of the rectangle denoted by small l is equals to 2x units and this particular length of 3x plus 3 units is the width of the rectangle.
00:57
So width of the rectangle denoted by small w is equals to 3x plus 3 units.
01:06
So using this formula, the perimeter of this rectangle will be equal to twice of length plus width.
01:16
That is two times of l plus double, which is given as equals to 146.
01:23
So now we will put length equal to 2x units and width equal to 3x plus 3 units in this equation.
01:34
So we get twice of 2x plus 3x plus 3 is equals to 146...
