Answer:
130units²
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
