Question

the perimeter of an idosceles triangle is 42 cm and its base is 3/2 times each of equal sides find the length of each side of triangle,are of triangle and height of triangle​

Answer 1

Answer:

3/2 times mean 1.5 times

let the equal sides be x each

therefore the base = 1.5x

perimeter = x+x+1.5x

3.5x=42

x=42/3.5 =12

base = 1.5*12=18 and each equal side= 12
