The length of a eectangle is 3/2 u oys greater then its width.if the width is w, which expression gives the perimeter

svet-max [94.6K]

Answer: The expression of perimeter will be

$3+4w$

Step-by-step explanation:

Since we have given that

Let the width of rectangle be w

Let the length of rectangle is given by

$w+\frac{3}{2}$

As we know the formula for "Perimeter of rectangle":

$\text{Perimeter of rectangle}=2(L+B)\\\\\text{Perimeter of rectangle}=2(\frac{3}{2}+w+w)\\\\\text{Perimeter of rectangle}=2(\frac{3}{2}+2w)\\\\\text{Perimeter of rectangle}=3+4w$

Hence, the expression of perimeter will be

$3+4w$
