ANSWER:-
GIVEN:
__________
The perimeter of the triangle ABC is 240m.
The length of the two sides are 78m and 50m
TO FIND:
____________
- The length of the side
- the length of the altitude
SOLUTION:-
_______________
In the above figure,AB=78m
BC=50m
The perimeter of the triangle is=AB+BC+AC
=>240m=(78+50)m+AC
=>AC=240m - 128m
=>AC=112cm
angle ADB =90°(altitude)
so,AD=√[(AB)^2+(BD)^2]
BD=BC/2=50m/2=25m
AD=√(78^2+25^2)
=√(6084+625)
=81.9m
hope it will help you friend

- Perimeter of triangular field ⇢ 240 m.
- Length of two sides ⇢ 78 m and 50 m.
- Perimeter of triangular field ⇢ 240 m.
✰ So, the third side is 112 m.
- a ⇢ 50
- b ⇢ 78
- c ⇢ 112
✰ Let the height be h m.
