Question

The perimeter of an isosceles triangles is 40 cm if 3 times the base is equal to 4 times the congurent sides find the length of each side of the triangle

Answer 1

Answer:

Step-by-step explanation:

in an isoceles triangle, two sides are equal

hence let the sides are a,b,b

a+2b=40

3a=4b

3(40-2b)=4b

120-6b=4b

120=10b

b=12

3a=4×12

a=48/3

a=16

16,12,12 are the sides of a triangle
