In order for Mateo to walk 1000 meters in his rectangular backyard, he must walk the length 25 times or the perimeter 10 meters. What is the are of his backyard in square meters?

Thanks!

"perimeter 10 meters "
I guess maybe you mean ten times but it is still nonsense

1000 = 25 L so L = 40 m

1000 = 10 ( L+w)
100 = 40 + w
so w = 60

area = L * w
obviously there is something wrong. width bigger than length
its supposed to be 10 times
