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?

1 answer:

7 0

B. No, the rectangle cannot have x = 20 and y = 11 because x + y ≠ 32

Perimeter = 2(l + w)
Perimeter = 64

Assuming: P = 64; w = 11 ; l = ?
64 = 2(l + 11)
64/2 = l + 11
32 - 11 = l
length = 21.

2/9×5=10/45
3/5×9=27/45
so 3/5 is bigger then 2/9

5/7×5=25/35
3/5×7=21/35

So 5/7 is larger than 3/5

So from least to greatest the numbers are
2/9 then 3/5 then 5/7

So your answer is A
