The perimeter of a rectangle is 400 meters. the length is 15 meters less than the width. find the length and width

Ok... Perimeter is = 2l + 2w

w being width and l being length.

We know that perimeter is equal to 400 so

400 = 2l + 2w

The length is 15 meters less than the width, so in notations, l = w - 15

We can substitute than in the equation to get 2(w-15) + 2w = 400

Expanding will give 2w - 30 + 2w = 400

Solving w gives w= 430/4 = 107.5 meters

Substituting in original equation for w to find l, 400 = 2l + 2(107.5)

400 = 2l + 215

2l = 185

l = 92.5 cm

Or you can just use the question to know that the length is 15 times less than the width, so 107.5 - 15 = 92.5

Length = 92.5 cm

Width = 107.5 cm

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
