Question

3. In AABC, angleA = 90°, AB = 14 cm, AC = 48 cm.
Find the
(i) area of AABC
(ii) length of perpendicular from A to BC​

Answer 1

Answer:

1. .336 cm²
2. .50cm

Step-by-step explanation:

$\huge{\underline{\underline{\mathfrak{Answer}}}}$

area of triangle ABC = 1/2 * base * height

1/2*14*48 = 7 * 48 = 336 cm²

length of BC

BC² = AC²+AB²

BC² = 48²+14²

BC² = 2304 + 196

BC ² =2500

BC² = 50 ²

BC = 50 cm...
