Hi Miura, First of all express the distance around the block, the perimeter, in meters. Let be the width of the block in meters. The block is 3 times as long as it is wide so what is its length in terms of W? What is the distance all the way around the block in terms of W? You know this distance so this gives you an equation in W. Solve for W. Penny | |||||||||||||||
