Answer:
Option D is correct
Value of x is, 5
Step-by-step explanation:
Properties of rectangle:
1. A rectangle is a 4-sided polygon.
2. It has two pairs of equal sides that are opposite to each other.
As per the statement:
Given the diagram SALE.
Here, SA = 3 units , LE = 3 units , AL = 5x-6 units and ES = 3x+4 units
⇒ units
By properties of Rectangle in SALE:
AL = ES
⇒
Add 6 to both sides we have;
Subtract 3x from both sides we have;
Divide both sides by 2 we have;
x = 5
Therefore, the value of x is, 5.
