Answer:
4.5 cm^2
Step-by-step explanation:
Area of trapezoid = ((base 1 + base 2) / 2) * height
According to the figure:
base 1 = 1.1 cm
base 2 = 3.4 cm
height = 2 cm
Now plugin into formula:
A = ((b1 + b2 ) / 2) * h
A = ((1.1 + 3.4) /2) * 2
A = ( 4.5/2 ) * 2
A = 2.5cm * 2cm
A = 4.5 cm^2

Total paid equals 30 desks multiplied by (the original price minus $17).
p=original desk price
Equation: $2010= 30(p - $17)
To Solve:
2010=30(p-17)
Use distributive property to multiply
2010=(30*p) - (30*17)
2010= 30p - 510
Add 510 to both sides
2520= 30p
Divide both sides by 30
$84= p
Original desk price was $84.
Hope this helps! :)
