Answer:
A = 4 cm²
Step-by-step explanation:
The area of a triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
b = AC = 3 +
= 4
h = BD
Calculate BD using Pythagoras' identity in Δ ABD
BD² = AB² - AD²
= (2 )² - (3
)²
= 20 - 18 = 2 ( take square root of both sides )
BD =
Then
A = × 4

= 2 ×

= 4 cm²
