Mathematics

The width of the rectangle is 30 units

Step-by-step explanation:

we know that

The perimeter of a rectangle is

P=2(L+W)

where

L is the length

W is the width

we have

$P=90\ units$

$L=15\ units$

The draw in the attached figure

substitute the given values in the formula of perimeter and solve for W

90=2(15+W)

45=(15+W)

W=45-15

$W=30\ units$

therefore

The width of the rectangle is 30 units

4. find the width of a rectangle with a perimeter of 90 and a length of 15. draw and label the recta
