​

Answer 1

Answer:

okkkkkkkkkkkkkkkkkkkkkkkkk

Answer 2

Answer:

a = 60 , b = 40cm and diagonal = 80 cm

perimeter of triangle = 60+40+80 = 180cm

semi perimeter = P/2 = 180/2 = 90

area of triangle =

\begin{gathered} \sqrt{s(s - a)(s - b)(s - c)} \\ = \sqrt{90(90 - 60)(90 - 40)(90 - 80)} \\ = \sqrt{90 \times 30 \times 50 \times 10} \\ = \sqrt{1350000} \\ = 300 \sqrt{15} \\ = 1,161.895(approx)\end{gathered}s(s−a)(s−b)(s−c)=90(90−60)(90−40)(90−80)=90×30×50×10=1350000=30015=1,161.895(approx)

area of parallelogram = 2*1,161.895 = 2,323.79cm²
