The length of a rectangle is 24 units. can the perimeter p of the rectangle be 60 units when its width w is 11 units?

No it cannot because the perimeter is the sum of all the sides and a rectangle has 4 sides so 24x2 + 11x2 = 70. So the perimeter would be 70 not 60.

Hope this helps :)

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)

You're doing something i dont know how to do but search up on google slope calculator maybe that will get you there
