Answer:
x = 2
Step-by-step explanation:
Firstly, calculate the area of the rectangle with the formula:
Length x width = area
(x+6) * 3 = 3x + 18
The formula for the area of a triangle is:
We can plug the known variables into the equation and get:
4 * (x + 4)
4(x + 4)
4x + 16
As the two areas are the same:
4x + 16 = 3x + 18
Subtract 3x from both sides of the equation:
4x + 16 - 3x = 3x + 18 - 3x
x + 16 = 18
Subtract 16 from both sides of the equation:
x + 16 - 16 = 18 - 16
x = 2
Hope this helps!
