Gloria is digging for fossils at a geological site. She has 120 meters of rope and 4 stakes to mark off a rectangular area. Which set of dimensions will create a rectangle using all the rope Gloria has with her? 12 m × 10 m
50 m × 10 m
60 m × 60 m
45 m × 10 m

B

Step-by-step explanation:

Let's go through each set of dimensions and test them. Keep in mind that two times the sum of the length and width of a rectangle yields the perimeter.

A) 2(12+10)=2(22)=44

B) 2(50+10)=2(60)=120

This works! Therefore, the correct answer is choice B. Hope this helps!

sorry, i can't understand your question. will later if you describe more clearly!
