The length of a rectangle is twice as long as the width. If the diagonal length of the rectangle is 60 cm, what is the perimeter of the rectangle (to the nearest centimetre)?
Provide a complete algebraic solution, including a supporting diagram.

And we can find the perimeter as:

And replacing the value given for x we got:

And for this case the perimeter would be approximately

Step-by-step explanation:

For this case we can assume that the lenght is 2x the width x and the diagonal is 60 cm.

From the picture given we have a right tirngle and we can set the following equation:

And solving for x we got:

And we can find the perimeter as:

And replacing the value given for x we got:

And for this case the perimeter would be approximately

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's
