Question

If length of the rectangle is three times of it’s width and perimeter of rectangle is 128cm. Find length

and width of rectangle by cramer’s rule.​

Answer 1

Answer:

Step-by-step explanation:

The perimeter is then w + 3w + w + 3w which adds up to 8w. So, since the perimeter is at most 128 cm, we can say 8w < 128 or w < 16.

We are looking for "the greatest possible value for the width" so w = 16
