Answer:
y = 9![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = ![\frac{1}{\sqrt{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%20%7D)
sin45° =
= ![\frac{9}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7By%7D)
Multiply both sides by y
y × sin45° = 9, that is
y ×
= 9
Multiply both sides by ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
y = 9![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)

Answer:
231cm²
Step-by-step explanation:
find the area of the rectangle. 12 x 11=132
find the area of the triangle. 9 x 11=99
add the two areas together. 99 + 132=231
