The side lengths of a rectangle are all multiplied by 5. What happens to its perimeter?

stiv31 [10]

Answer:

The perimeter is multiplied by 5.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with sides l and w is given by:

$P = 2(l + w)$

The side lengths of a rectangle are all multiplied by 5.

This means that $l = 5l, w = 5w$ . So

$P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)$

What happens to its perimeter?

The rate is:

$\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5$

The perimeter is multiplied by 5.

Maksim231197 [3]

(3,5)....x1 = 3 and y1 = 5
(1,3)....x2 = 1 and y2 = 3

slope formula : (y2 - y1) / (x2 - x1)
slope = (3 - 5) / (1 - 3) = -2/-2 = 1 <== slope is 1
