Pls help ..
No trolls pls I need this-

1800 square feet

Step-by-step explanation:

Area of composite figure

Figure 1:

length = 27 ft

Width = 24 ft

Area of figure1 = length * width

                        = 27 * 24

                        = 648 square feet

Area of figure II:

              length = 27 ft

              Widht = 32 ft

Area of figure II = 27 *32

                          = 864 square feet

Area of figure III:

    base = 18 ft

     height = 32 ft

Area of composit figure = 648 + 864 + 288

                                        = 1800 square feet

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
