Question

15 m
7. Triangle ABC and Triangle ADC are two right triangles with hypotenuse AB and AD
respectively. Given that AB = CD = 20 m, AC = 15 m and area of Triangle ABD =
240 m2, find height h
20 m​

Answer 1

First As you know Area of triangle ABD is 240, so find its base by 1/2 x base x height = 240

then you'll get the length BD. Now find BC by BD-CD

Now you have all sides of triangle ABC

Now Simply Use heron's formula for area of ABC

Then again find the height by using 1/2 x base x height

and you'll get the h
