Question

Use the diagram to determine which statement is true

Answer 1

The answer is d.

Finding area of ABCD :

1. Find side length

• side = √3² + 4²
• side = 5

2. Apply formula to find area

• area = 5²
• area = 25

Finding area of GHIA :

• area = 4²
• area - 16

Finding area of DEFG :

• area = 3²
• area = 9

Now, let's see whether is true.

• Area (ABCD) - Area (GHIA) = Area (DEFG)
• 25 - 16 = 9
• 9 = 9

∴ Hence, it is proved √
