yan [13]
S=2d

4s+3d=300000-80000

4s+3d=220000, now using s=2d in this equation you get:

4(2d)+3d=220000

8d+3d=220000

11d=220000

d=20000

So each daughter gets 20000 and each son gets 40000.

S (ABCD) = S (ABC) + S (ADC)

_____________________________________________

<h2>Reminder :</h2>

Area of the triangle = ½ × base × height

_____________________________________________

Thus :

S (ABCD) = ( \frac{1}{2}   \times 10 \times 3) + ( \frac{1}{2}  \times 10 \times 5) \\

S (ABCD) = 15 + 25

S (ABCD) = 40 \:  \:  {cm}^{2}

There you go...

Have a great day ❤
