The perimeter of the rectangle below is 166 units. Find the value of y.
4y + 2
Sy
The value of y is 9.
Perimeter is the total length of the boundary of any closed shape. It is basically the sum of all the sides of a given figure.
Perimeter of a rectangle is given by [ 2( l + b ) ] or (2 l + 2 b ) or
( l + l + b + b), here l and b represent the length and breadth of the given rectangle.
Perimeter of the given rectangle = 166 units ( given )
Length of the given rectangle = 5y ( given )
Breadth of the given rectangle = (4y + 2) ( given )
By putting values in the formula, we get
perimeter = 2 ( l + b )
166 = 2 [ (5y) + (4y + 2) ]
166 = 2 [ 5y + 4y + 2 ]
166 = 2 [ 9y + 2 ]
166 = 2*9y + 2*2
166 = 18y + 4
166-4 = 18y ( moving 4 to other side thus changing the sign to negative )
162 = 18y
162/18 = y ( moving 18 to other side for further solution )
y = 9
Therefore, the value of y for which the perimeter of the given rectangle is 166 units is 9.

The value of y is 9.
The whole length of any closed shape's boundary is known as its perimeter. In essence, it is the total of a given figure's sides.
A rectangle's perimeter can be calculated using [2(l + b)] or (2 l + 2 b) or
(l + l + b + b), where l and b stand for the provided rectangle's length and width
The rectangle's perimeter is 166 units ( given )
The rectangle's length is 5y ( given )
Given rectangle's width equals (4y + 2) ( given )
When we enter values into the formula, we obtain
perimeter = 2 ( l + b )
166 = 2 [ (5y) + (4y + 2) ]
166 = 2 [ 5y + 4y + 2 ]
166 = 2 [ 9y + 2 ]
166 = 2*9y + 2*2
166 = 18y + 4
166-4 = 18y ( moving 4 to other side thus changing the sign to negative )
162 = 18y
162/18 = y ( moving 18 to other side for further solution )
y = 9
Therefore, the value of y for which the perimeter of the given rectangle is 166 units is 9.

The algebraic solution for the variable x is as follows:
x = 9 / 2. How to find the variable x in the equation?The equation is represented as follows;
2 / 5 (2 - x) = - 1 / 3 x + 1 / 2
open the bracket on the left side
2 / 5 (2 - x) = - 1 / 3 x + 1 / 2
4 / 5 - 2x / 5 = - 1 / 3 x + 1 / 2
Add 1 /3 x to both sides
4 / 5 - 2x / 5 = - 1 / 3 x + 1 / 2
4 / 5 - 2x / 5 + 1 / 3 x = - 1 / 3 x + 1 / 3 x + 1 / 2
4 / 5 + 1 / 3 x - 2 / 5 x = 1 / 2
4 / 5 + 5x - 6x / 15 = 1 / 2
4 / 5 - x / 15 = 1 / 2
subtract 4 / 5 from both sides
4 / 5 - 4 / 5 - x / 15 = 1 / 2 - 4 / 5
- x / 15 = 5 - 8 / 10
- x / 15 = - 3 / 10
cross multiply
- x / 15 = - 3 / 10
-10x = - 45
divide both sides by -10
x = 45 /10
x = 9 / 2
Therefore, the algebraic solution for the variable x is 9 / 2.

For the parallel lines ED and FG, where EF is the transversal,
The angle DEF and the angle EFG are same-side interior angles.
By the same-side interior angle theorem, we can say that the interior angles on the same side of the transversal are supplementary (the sum of the angles is 180°).
∠DEF = 13x°
∠EFG = 17x°
∠DEF + ∠EFG = 180°
13x + 17x = 180

x = 6
∠DEF = 13x = 13*6 = 78°

Now, using standard perimeter as well as area formulas of a rectangle. Therefore, the equation can become:
Let us assume, the width of the rectangle be 'w' inches
The length of a rectangle be (9w - 11)
As we know, perimeter of a rectangle is 2(l + w)
Substitute the calculated parameters in the perimeter formula:
18 = 2(9w - 11 + w)
⇒ 9 + 11 =10w
⇒ w = 2 inches and l = 7 inches
Then, the calculated width is 2 inches and length is 7 inches.
