Question

The perimeter of a rectangle is 64 units. Can the length x of the rectangle can be 20 units when its width y is 11 units?

Answer 1

Answer:No, the rectangle cannot have x=20 and y=11 because x+y does not equal 64

Explanation:

Answer 2

no it can't, because:
P= 2(l+w)
therefore if x=20
P=2(20+11)
P=62 does not equal to 64.
x must be 21 for the equation to be true.
