anonymous · Answer

In a rectangle, AD = BC

And AB = CD

anonymous · Answer

Now, Perimeter of the rectangle is given as:

Perimeter = AB + BC + CD + DA

Perimeter = AB + BC + AB + BC

Perimeter = 2AB + 2BC

Perimeter = 2(Length + Width)

triciaal · Answer

from the diagrams above you see the perimeter, P = 2( length + width)
given P = 90 and length = 15 plug the numbers and solve for the width

anonymous · Answer

So, you are given Perimeter as 90 and length as 15..

So,

$90 = 2(15 + Width)$

$45 = 15 + Width$

Subtract 15 from both the sides, and you will get your Width..
