Let a represent total area and let w represent width $a=1.6w^2$

Work Step by Step

We can find this equation because we know that the length is 1.6 times the width, so we can model that through l=1.6w. We do not know what width is so we can leave it as w. The formula of area of a rectangle is A=(L)(W) We can substitute the values to find the answer A=(L)(W) A=(1.6w)(w) $A=1.6w^2$
