Question

Area of an isoceles triangle is given 12 cm square if one of its side 5 cm find its base

Answer 1

Both sides are 5.
The base is x
The area is (1/2)x h=12
xh=24
The height is one leg of a right triangle, half the base another leg, and the hypotenuse is 5.
This has to be a 3-4-5 right triangle.
The base is 3, but that is the base of half of the isosceles triangle. The whole base is 6.
The height is 4 in any case.
The area is (1/2)*24=12 cm^2
Height is 4 and base is 6
