I would start by saying how much I enjoyed this lesson and how it has helped me in many ways I would also like to state how it was difficult at first but once I started to understand it, it became really easy and would like to thanks the teacher for teaching it.
Divide by 2 and find out.
4/9 / 2
Multiply by its reciprocal:
4/9 * 1/2
Multiply the numerators and denominators together:
4/18
4/18 does not equal 8/18, so 4/9 isn't half of 8/18.
We need to see the "given system".
Answer:
A ≈ 40.3 cm²
Step-by-step explanation:
The area of right Δ ACD is calculated as
A = 
bh ( b is the base and h the perpendicular height )
Here A = 50.5, b = CD and h = AC , then
× 14 × AC = 50.5
7 AC = 50.5 ( divide both sides by 7 )
AC ≈ 7.214
The area of Δ ABC is calculated as
A = × BC × AC × sin36°
= 0.5 × 19 × 7.214 × sin36°
≈ 40.3 cm² ( to 3 sf )
there are 6 faces multiply 25 by 6
25*6=150cm^2
