He width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units

No because from what I understand,

2w + 2l = p            so

2(20) + 2(11) = 64    if that was true, both sides would be equal.

40+22+=64

62=64            and they are not.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
