Question

-. The base of an isosceles triangle is 8 cm long and each of its equal sides
measures 6 cm. The area of the triangle is
​

Answer 1

s = 1/2(a + b + c)

Area = square root [s (s - a) (s - b) (s - c)]

area=

$(10(10 - 8)(10 - 6)(10 - 6)) \\ \\ = 10 \times 2 \times 4 \times 4 \\ \\ = 320$

area=320sqcm
