Question

find the are of the isosceles triangle has perimeter 30 cm and each equal side is 8 cm find area of the triangle​

Answer 1

Answer:

equal sides =8cm

perimeter=30cm

8+8+x=30

16+x=30

x=14cm

semi perimeter=30/2=15

$area \: of \: triangle \: = \sqrt{s(s - a)(s - b)(s - c)} \\ \sqrt{15(15 - 8)(15 - 8)(15 - 14)} \\ = \sqrt{15 \times 7 \times 7 \times 1} \\ = 7 \sqrt{15}$
