First, you need to substitute the value of x in all of the x spots.
2x+3
2(3)+3. Us PEMDAS to solve the problem.

550-500 is not 500 it’s 50
square meter is the SI unit of area.
Answer:
12
Step-by-step explanation:
The formula for the tangent of an angle is the length of the opposite side divided by the length of the adjacent side. Therefore, the tangent of angle x is 420/2000=0.21. Taking the arctangent of that to get the angle, you get about 12 degrees. Hope this helps!
Perimeter (P) = 2L + x
4900 = 2L + x ⇒ 4900 - x = 2L ⇒ 
= L
Area (A) = L · x
A = () (x)
=
