Judith is digging for sandstone at a geological site. She has 160 meters of rope and 4 stakes to mark off a rectangular area. Which set of dimensions will create a rectangle using all the rope Judith has with her?
You have to use the Formula Perimeter = 2(Length + Width). Simply plug in the measurement given as your options and do the math. So, the answer looks like this. P = 2(70 + 10), P = 2 (80), P = 160
