Work out the area of triangle ABC.
B.
25 cm
A
32 cm
D
2 cm

Step-by-step explanation:

ΔADB is a right angled triangle. So, use Pythagorean theorem.

Altitude² = hypotenuse² - base²

               = (2√5)² - (3√2)²

              = 2²* (√5)² - 3²*(√2)² = 4*5 - 9*2 = 20 - 18 = 2

Altitude = √2

Base of ΔABC = 3√2 + √2 = 4√2 cm

Area =
