Answer:
L = 3√5
Step-by-step explanation:
A square and a rectangle have equal areas.
Area of a square = Area of a rectangle
L² = H * W
If the dimensions of the rectangle are 15 units by 3 units,
L² = 15 * 3
L² = 45
Determine the length of the side of the square.
L = √45
L = 3√5
Answer:

Step-by-step explanation:
Assuming, right and up are positive directions.
The given parent function, 
Let
be the function when the parent function is stretched by a scale factor of 2.
So, 

Let
be the function when
is translated
units right.
So, 

Again, let
be the function when
is translated 4 units up.
So, 

So, the resulting function,
.
Hence, option (1) is correct.
