Question

the perimeter of isosceles triangle is 32cm.the ratio of the equal side to it's base 3:2. find the area of the triangle
​

Answer 1

Step-by-step explanation:

let equal sides be 3x,2x

area=1/2base×height =32cm

1/2×3x×2x=32

3x=32

X=32/3

1.67

Answer 2

Answer:

Given,

Perimeter if isosceles triangle = 32cm

Ratio of equal sides to base = 3:2

Let the sides of the triangle be 3x,3x & 2x

According to the question,

3x + 3x + 2x = 32cm

8x = 32cm

x = 4cm

Therefore equal sides = 3x = 4 * 3 = 12 cm

& Base = 2x = 2 * 4 = 8cm

Area of triangle = 1/2 * base * Height

Area of given triangle = 1/2 * 8 * 12

= 4 * 12 = 48cm
