16 m × 10 m
80 m × 80 m
65 m × 10 m
70 m × 10 m

Answer 1

Answer:

70 m × 10 m

Step-by-step explanation:

At a geological site, Judith is digging for sandstone. To mark off a rectangular area, Judith has 160 meters of rope and 4 stakes.

We have to choose from the given dimensions of rectangles where Judith can use all the rope she has to cover the rectangular area.

It is clear from the given conditions that the perimeter of the rectangular area should be exactly 160 meters.

So, the required dimensions of the rectangle are 70 m × 10 m, because the perimeter of this rectangle is exactly 160 meters. (Answer)
