Find the area of a rectangle having a perimeter of 182 yards and a width 20 yards shorter than twice its length

Studentka2010 [4]

Let the length be $l$ in this equation.

We know that the perimeter of a rectangle is $w2 + l2 = P$

Width is defined in terms of length, so we know $w = l2 - 20$

We can substitute this value of w into the formula for perimeter to find the length.

$(l2 - 20)2 + l2 = 182$

$l4 - 40 + l2 = 182$

$l4 + l2 = 222$

$l6 = 222$

$l = 37$

So the length is 37. Now that we've found the length, we can go back to the Perimeter formula again and find width.

$w2 + (37)2 = 182$

$w2 + 74 = 182$

$w2 = 108$

$w = 54$

Width is 54. Now with both of these values found, we can calculate area with the formula $l * w = A$

$37 * 54 = A$

$1998 = A$

So the area of the rectangle is 1998 yards^2.

Find the distance for (3,5) and y=3x+2

Natali5045456 [20]

There are standard formulas for this type of problem. However, it can also be solved by a combination of simple steps.

First, the shortest distance from the point (3,5) to the line y = x +4 (line1) will be along a straight line perpendicular to line1. Give the perpendicular line the name line2. Since the slope of line1 is 1, the slope of line2 will be -1.

Second, since line2 must go through (3,5) and also have a slope of -1, the point slope form can be used for line2:
y - 5 = (-1) (x -3)
So the equation of line2 is y = -x +8.

Third, the point of intersection of line1 and line2 can be found by solving the set of equations:
y = x +4
y = -x + 8
The solution of this set of two equations is x = 2, y = 6 i.e. the point (2,6) .

Fourth, the distance formula can be used to find the distance between (3,5) and (2,6)
d = sqrt( (3-2)2 + (5-6)2 ) = sqrt(2)
This is the desired distance.
