Question

Triangle ABC is an isosceles triangle with AB = AC = 7.5m and BC = 9 cm. The height from A to BC , is 6 cm . Find the area of triangle ABC . What will be the height from C to AB and AD

Answer 1

Answer:

find it by the use of pytha 67.5

Answer 2

Given :

• Triangle ABC is an isosceles triangle with AB = AC = 7.5m and BC = 9 cm.
• The height from A to BC, is 6 cm.

　

To find :

• What is the area of triangle ABC.
• What will be the height from C to AB and AD.

　

Calculations :

→ Area of ∆ABC = 1/2 × B × H

→ Area = 1/2 × BC × AD

→ Area = 1/2 × 9 × 6

→ Area = 27 cm²

　

• Length of CE .

　

→ Area of ∆ABC = 1/2 × B × H

→ Area = 1/2 × AB × CE

→ Area = (1/2) × 7.5 × CE

→ Area = 3.75
