Question

the parameter is an isosceles triangle is equal to 40 cm. The base is two third of the sum of equal sides. find the area of triangle?
​

Answer 1

Step-by-step explanation:

Let the equal sides of triangle be x and x.

The base of triangle be 2x ×2/3 = 4x/3.

Sum of all sides = Perimeter of triangle

4x/3 + 2x = 40 cm

x = 12 cm

4x/3 = 16 cm

Area of triangle = 244√22 cm

= 1144.5 cm^2 (approx.)
