Subject: geometry hey i'm just wonderin if u can answer this question ok [a thin wire 20 centimeters long is formed into a rectangle. if the width of this rectangle is 4 centimeters, what is the length?] |
Hi Trisha,
Make the rectangle this way. Cut off a piece of the wire 4 cm long for one end and another piece 4 cm long for the other end. How much wire is left? You have to divide this remaining piece in half for the two sides. How long are they?
