Question

In triangle abc ad is an altitude BC is 8 cm and area of ABC is 40 cm therefore find AD​

Answer 1

Let x be AD.

(8x)/2 = 40

8x = 80

x = 10

AD is 10cm.

Answer 2

`\huge\boxed{\sf Height = 10\ cm}`

Explanation:

Altitude = Height = AD = ?

Base = 8 cm

Area = 40 cm²

`\rule[225]{225}{2}`

Area = 1/2 (Base * Height)

40 = 1/2 ( 8 * Height)

40 = 4 * Height

Dividing both sides by 4

40 / 4 = Height

Height = 10 cm

`\rule[225]{225}{2}`

Hope this helped!
