The total length of the wire used = 144 cm

The height of each isosceles triangle = 24cm and the two equal sides = 26 cm each. So....using the Pythagorean Theorem, 1/2 of the base = sqrt(26^2 - 24^2) = sqrt(100) = 10cm

So.......the whole base = 20 and the perimeter of each triangle = 20 + 2(26) = 72 cm

And the area of the isosoceles triangles = 1/2(base) x ht = 10cm x 24cm = 240cm^2
