Hi there!
The answer is D.
We need to isolate each square root. We can simply do this by adding
to both sides of the equation.
When we isolated the square roots, our equation looks like this:
Now we can easily square both sides of the equation, which would have been much harder earlier.

Answer:
The correct answer is c) 18 centimeters
Step-by-step explanation:
Given:
A = 18 cm²
We know that the formula for calculating area of a rectangle is
A = a · b where a is length and b is width
Possible choices is 6 · 3 and 9 · 2
Formula for calculating perimeter is
P = 2 ( a + b)
P₁ = 2 (6 + 3) = 2 · 9 = 18 cm²
P₂ = 2 (9 + 2) = 2 · 11 = 22 cm²
The obvious choice is P₁ = 18 cm²
God with you!!!
