The length of a rectangle is three times its breadth if the breadth is decreased by 2 m and breadth increased by 4 m the area of

White raven [17]

Answer:

Let the breadth is x, then the length is 3x.

A = lw = 3x*x = 3x²

<u>The breadth is decreased by 2 m: </u>

w = x - 2

<u>The length is increased by 4m: </u>

l = 3x + 4

(x - 2)(3x + 4) = 3x² - 1/3(3x²)
3x² + 4x - 6x - 8 = 2x²
x² - 2x - 8 = 0
x² - 2x + 1 = 9
(x - 1)² = 3²
x - 1 = 3
x = 4

The breadth was 4 m and the length 12 m

What is the length of the line segment with end points (5, -7) and (5, 11)

Law Incorporation [45]

Answer:

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (5, -7) and (5, 11). Substitute:

$d=\sqrt{(5-5)^2+(11-(-7))^2}=\sqrt{0^2+18^2}=\sqrt{18^2}=18$
