Ashley is digging for rocks at a geological site. she has 140 meters of rope and 4 stakes to mark off a rectangular area. which set of dimensions will create a rectangle using all the rope ashley has with her?

ok consider a rectangle with two sets of equal sides

call one side of a set x

and one side of the other set y

we know she has 140 meters of rope so perimeter of the rectangle = 140

so 2x + 2y= 140

hence X = (140- 2y)/2

the dimensions have to satisfy the above equation

i think the answer is b.

step-by-step explanation:

not 100% sure though.
