Question

The perimeters of an isosceles triangle is 50 cm. The ratio of the equal side to its base is 4:2 find the area of the triangle ​

Answer 1

Answer:

100cm^2

Explanation:

Perimeter of triangle :-50cm

Ratio of equal side to its base=4:2

Let the sides be 4x, 4x,2x

Therefore...

4x+4x+2x=50

10x=50 cm

X=50/10

x=5

So... 4x=4×5=20

2x=2×5=10

Sides are 20cm, 20cm,10cm

Area of the isosceles triangle = (h×b)/2

= (20×10)/2

=200/2

=100cm^2
