Question 62507
{{{Area of a rectangle = length * width}}}The * means times.

In this problem you already have the area and length so the formula gives
{{{55 = 7 * width}}} Divide both sides of the equation by 7
{{{55/7 = 7 * width /7}}}
{{{55/7 = width }}}Using your calculator divide 55 by 7 to get a width of approximately 7.86 metres.
