Please help me!! If the area of square 1 is 250 units2, and the area of square 3 is 120 units2, what is the area of square 2? Explain your reasoning.

130units²

Step-by-step explanation:

The question lacks the required figure. Find the figure attached:

Given

Area of square 1 = 250units²

Area of square 3 = 120units²

Area of a square = L²

L is the length of one side of the square

Get the length of each side of the square

For square 1

A1 = L1²

250 = L1²

L1 = √250

Get that of square 3

A3 = L3²

120 = L3²

L3 = √120

Required

Area of square 2

Before we can get the area of square 2, we need to get the side length using pythagoras theorem

L₂² = L₁² - L₃²

L₂² = (√250)²-(√120)²

L₂² = 250-120

L₂²  = 130

Since the area of the square A is L₂² , then the required area is 130units²
