Answer:
35 ft^2
Step-by-step explanation:
Area of the first rectangle
A = 8 x 2 = 16 ft^2
area of the second rectangle
A = 5 x 2 = 10 ft^2
area of the square
A = 3^2 = 9 ft^2
total area
A = 16 + 10 + 9 = 35 ft^2
The scale length is 9cm and the scale is 6cm/15ft which is 3cm/5ft, so we can say:
9cm(5ft/3cm)=15ft for the length
If you wanted the width too...
4cm(5ft/3cm)=20ft/3 (6'8", 6ft 8in)
