Question

The length of the sides forming a right angle of a triangle are 12 cm and 17 cm . find the area of the triangle?​

Answer 1

Answer:

102 cm²

Step-by-step explanation:

Length of the base = 12 cm

Length of the height = 17 cm

Length of the third side = a² + b² = c² = 12² + 17² = c²

= 144 + 289 = c²

= 433 = c²

c = √433 = 20.8 cm

Area = (1/2) × b × h = (1/2) × 12 × 17 = (1/2) × 204 = 204/2 = 102 cm²

Answer 2

heya mate!!! nice to meet ya again...

here is your answer

area of Δ = $\frac{1}{2}$ * base * height

= $\frac{1}{2}$ * 12 * 17

= $\frac{1}{2}$ * 204

= 102$cm^{2}$ is your answer friend
