A 240-centimeter board is to be cut into two pieces so that the longer piece is twice as long as the shorter piece. Find the length of each piece.

Answer (3)

you need two pieces and 1 has to be 2x longer than the other set x as the smaller piece (easier to always go with the smaller value as x) the other piece is 2x (double in size) your equations would be 3x=240>>> x= 60
so smaller piece/ x= 60 bigger piece/ 2x= 120

If the side lengths are 240, then the answer is one length is 240 and one length is 120 cm

The shorter piece of the board is 80 centimeters long, while the longer piece is 160 centimeters long. We found this by setting up an equation based on the relationship between the lengths of the two pieces. This solution used basic algebra to solve for the unknown lengths.
