Question

The perimeter of an isosceles
triangle is 42 cm and its base
is 3/2 times each of the equal
sides. Find the length of each
of the triangle area of triangle and the height of the triangle​

Answer 1

Answer:

Let the three sides be x, x, y (y being the unequal side which is base)

y = 1.5x (given)

Perimeter = x + x + 1.5x = 42

3.5x = 42

x = 42/3.5 =12

The three sides are 12, 12, 1.5(12)

12, 12, 18

From heron’s formula:

Area of triangle = root of {s(s-a)(s-b)(s-c)} (a, b, c are sides and

s is the semi perimeter which is (a+b+c)/2)

Root of {21(9)(9)(3)}

Answer is 27(root7)

hope it helps u

Answer 2

➼ Hence, height of the triangle is 7.94 cm.
