Respuesta :
Answer:Width = 15 units .
Step-by-step explanation:
Given : The width of a rectangle is 4 more than half the length. If the perimeter of the rectangle is 74,
To find : what is the width.
Solution : We have given perimeter of the rectangle is 74,
Let the Length = x .
According to question :
The width of a rectangle is 4 more than half the length.
Width = 4 + [tex]\frac{x}{2}[/tex].
Perimeter = 2 length + 2 width .
Plugging the values,
74 = 2 ( x ) + 2 (4+[tex]\frac{x}{2}[/tex]).
74 = 2x + 8 + x .
Combine like terms
74 = 2x +x + 8.
74 = 3x +8.
On subtracting both sides by 8.
74 -8= 3x .
66 = 3x
On dividing both sides by 3
x = 22.
Width = Width = 4 + [tex]\frac{22}{2}[/tex].
Width = 4 +11.
Width = 15 units .
Therefore, Width = 15 units .
