Question

the area of a triangular flag with two equal sides is 2700 square cm what is the perpendicular distance from the tip of the flag to the third side which is 60 CM in length

Answer 1

Answer:

ıllıllı нєу ıllıllı

Step-by-step explanation:

We know the area of a triangle = 1/2 x b x h

In this problem:

b = 60 cm

h is perpendicular distance to the tip of the flag

1/2 x 60 x h = 2700

30h = 2700

h = 2700

h = 90 cm

Answer 2

Answer:

90 cm is the height.

Step-by-step explanation:

They gave you the area of the triangle & base of it & also it is an isosceles triangle.

Area of Triangle = Half of product of base & height = 1/2(bh) ( where 'b' is breadth of triangle& 'h' is height of triangle)

Now simply substitute the values given in the question in this formula.

Given, Area = 2700 square cm & base = 60 cm

So, 2700 = 1/2(60 * h)   [Now transpose'1/2' from R.H.S. to L.H.S. & it will become '*2'}}

2700*2 = 60*h

5400 = 60*h

5400/60 = h

h = 90 cm

Therefore the perpendicular distance/height = 90 cm.
