Homework help

Hi could someone please help me with this question I genuinely don't understand 🥲

There's the question!

To find…
Width of rectangle BD:
Use tan = opposite/adjecent to get BD
Which means…
Tan(60) = BD/7
7√3 = BD
Height of rectangle BF:
Since the two triangles are similar (due to the fact we know there’s a rectangle between them), we can use the similar triangle method to get BF.
Which means…
If BD -> AF is by dividing by (7√3)/6
Therefore CD -> BF is 7 divided by (7√3)/6 as well
Therefore BF = 2√3
Perimeter of BDEF:
Basically BF + FE + ED + DB
Which is…
2√3 + 2√3 + 7√3 + 7√3
= 18√3 cm
Area of BDEF:
Basically BF x BD
Which is…
2√3 x 7√3
= 42 cm^2
I hope this helps! I haven’t double checked my answer so I’m not fully sure if this is correct, but I know the method is definitely correct.

Omg thank you so much ! It was right 🙂 , also to find AF why did you divide by 6? Tysmmmm
