Hi,

     .

The length of a rectangle is six times its width(x) . 

If the perimeter of the rectangle is 140 cm, find its area 

P = 2L + 2W

Let x be the width of the rectangle

Write as You Read:

140cm = 2(6x) + 2x

140cm = 14x

x = 10cm, the width.  The length is 60cm 6%2A10     and 120cm%2B+20cm+=+140cmchecks

A = (10cm)(60cm) = highlight_green%28600cm%5E2%29

  Wish You the Best in your Studies.
