Question

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

Answer 1

Step-by-step explanation:

Perimeter of triangle is 50cm

Ratio of equal side to its base=4:2

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

Therefore...

4x+4x+2x=50cm

10x=50cm

x=50/10

x=5

so..4x=4×5=20

2x=2×5=10

sides are 20cm,20cm,10cm

Area of an isosceles triangle=(H×B)/2

= (20×10)/2

= 200/2

= 100cm^2
