Identify the area of the figure rounded to the nearest tenth. HELP?!! I don't understand!! Please help and show your work!!
Alex73 [517]

Answer:

67.5\ cm^{2}

Step-by-step explanation:

we know that

The area of the figure is equal to the area of rectangle (figure 1) plus the area of trapezoid (figure 2)

see the attached figure to better understand the problem

The area of the rectangle is

A=15*3=45\ cm^{2}

The area of the trapezoid is

A=\frac{1}{2}[(15-9)+3)](8-3)

A=\frac{1}{2}[6+3)](5)=22.5\ cm^{2}

The area of the figure is

45\ cm^{2}+22.5\ cm^{2}=67.5\ cm^{2}

A grocery store charges $3.00 for 4 two-liter bottles of lemonade. David has $12.00 in his wallet. Since David is having a party
nevsk [136]
No because he will be $3.00 short.
So it is $0.75 a bottle. So then you multiply $0.75 by 20. You get $15.00
So David will not have enough in his wallet.
