Answer:
225 square meters
Step-by-step explanation:
Area of a square:
A = w², where w is the width of the square
Plug in values:
A = 15m²
A = 225 square meters
When y varies inversely as x it can be expressed as follows:

If we write the general equation for this

When y=3 and x=4 we can calculate de value of A

Then the equation that describes an inverse variation between x and y is_
