Question

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

Answer 1

Answer: No.

Step-by-step explanation:

The perimeter P of rectangle with length x and width w is given by:-

$P=2(x+w)$

If width of rectangle is 20 units and length of rectangle is 11 units, then the perimeter of rectangle is given by:-

$P=2(11+20)\\\Rightarrow\ P=2(31)\\\Rightarrow\ P=62\neq64\ units$

Hence, it can not possible that if width of rectangle is 20 units the perimeter P of the rectangle be 64 units when its length x is 11 unit

Answer 2

20+20+p+p=62

when "p" equals 11 is false. the corect answer would be p=12 to get 64
