A soccer goal net has the shape shown.

If the netting has 5 cm by 5 cm square gaps, what is the total length of cord needed to make the back of the rectangle of the net?

Thanks for the help.

To make a mesh every 5 cm on the 5 meter side (that is, going down): change the 5 meters into cm, giving 500 cm.

Divide 500 cm by 5 cm, giving 100 ---> however, you must add 1 to get the correct number of threads.

Each of the 101 threads is 2 meters long ---> 202 meters.

To make a mesh every 5 cm on the 2 meter side (that is, going across): change the 2 meters into cm, giving 200 cm.

Divide 200 cm by 5 cm, giving 40 ---> again, you must add 1 to get the correct number of threads.

Each of the 41 threads is 5 meters long ---> 205 meters.

Adding, you will need at least 407 meters of cord.
