Question

The width of a rectangle is 12 units. Can the perimeter x of the rectangle can be 60 units when its length y is 18 units? (4 points)

No, the rectangle cannot have x = 60 and y = 18 because x + y is less than 60.
No, the rectangle cannot have x = 60 and y = 18 because x + y is less than 24.
Yes, the rectangle can have x = 60 and y = 18 because x = 12 + 2y.
Yes, the rectangle can have x = 60 and y = 18 because x = 24 + 2y.

Answer 1

perimeter is = to 2*length + 2*width
you are given a proposed perimeter of 60 and a width of 12, inset and solve to see if it is true
2(12) + 2L = 60
solve for L and compare to answers

Answer 2

Okay, Thank you.
