A=A trapeze+ A rectangular trapeze
A= (6.5+3.2)*4.5/2 + (1.8+4.5)*4.5/2= (9.7+6.3)*4.5/2=16*4.5/2=8*4.5=36 m^2
Answer:
![a=6](https://tex.z-dn.net/?f=a%3D6)
Step-by-step explanation:
Given equation:
![-8+\sqrt{5a-5}=-3](https://tex.z-dn.net/?f=-8%2B%5Csqrt%7B5a-5%7D%3D-3)
Solving for unknown variable ![a](https://tex.z-dn.net/?f=a)
Adding 8 both sides by additive property of equality.
![+8-8+\sqrt{5a-5}=-3+8](https://tex.z-dn.net/?f=%2B8-8%2B%5Csqrt%7B5a-5%7D%3D-3%2B8)
![\sqrt{5a-5}=5](https://tex.z-dn.net/?f=%5Csqrt%7B5a-5%7D%3D5)
Squaring both sides to remove the square root.
![(\sqrt{5a-5})^2=5^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B5a-5%7D%29%5E2%3D5%5E2)
![5a-5=25](https://tex.z-dn.net/?f=5a-5%3D25)
Adding 5 both sides by additive property of equality.
![5a-5+5=25+5](https://tex.z-dn.net/?f=5a-5%2B5%3D25%2B5)
![5a=30](https://tex.z-dn.net/?f=5a%3D30)
Dividing both sides by 6 to isolate ![a](https://tex.z-dn.net/?f=a)
![\frac{5a}{5}=\frac{30}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5a%7D%7B5%7D%3D%5Cfrac%7B30%7D%7B5%7D)
∴ ![a=6](https://tex.z-dn.net/?f=a%3D6)
