Question

rectangles perimeter and it's area have the same numerical value. the width of the rectangle is 3 units . what is the length of the rectangle in units?​

Answer 1

Explanation:

2(x+y)=parameter

xy=area

If area=parameter then 2(x+y)=xy.

If y=3, then

2(x+3)=3x

2x+6=3x

X=6

now, let’s double check.

6*3=18

2(3+6)=18
