Can someone plz with this question idk how to do it im stooopid

96 square units (choice B)

Explanation:

Triangle OBI has a base of OI = 12 units along the horizontal component, and CB = 8 is the vertical component or the height.

area of triangle OBI = 0.5*base*height

area of triangle OBI = 0.5*12*8

area of triangle OBI = 48 square units

Now find the area of the trapezoid GNIO. The two horizontal components are the parallel bases GN = 4 and OI = 12. The height of this trapezoid is the vertical component CD = 6, where point D is added on to be at location (0,-6) on the graph.

area of trapezoid = (height*(base1+base2))/2

area of trapezoid GNIO = 6*(4+12)/2

area of trapezoid GNIO = 48

Coincidentally, the triangle and trapezoid both have the same area

The last thing to do is add the two areas of the triangle and trapezoid

total area = (area of triangle OBI) + (area of trapezoid GNIO)

total area = (48) + (48)

total area = 96 square units

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
