Answer:
The correct answer is choice C.
Step-by-step explanation:
To find the area of the arrow, we must add together the areas of the rectangle and the triangle that make up the arrow. The rectangle has a length of 10 inches and a width of 4 inches, and the triangle has a base of 8 inches and a height of 2 inches. Using this information, we can plug numbers into the following formula:
Area of arrow = area of rectangle + area of triangle
Area of arrow = (10*4)+(1/2*8*2)
Area of arrow = 40 inches squared + 8 inches squared
Area of arrow = 48 inches squared
Therefore, the correct answer is option C, 48 square units (in this case, inches).
Hope this helps!

Can you attach the figure?
Step-by-step explanation:
7200 Kilometers in two hours. 4,320 kilometers in 6 hours.
Answer: 12 metres
Step-by-step explanation:
The scale factor used for the model is 1 : 30.
This means that for any 1cm on the model, the real boat would be 30 cm.
If the height is 40 cm on the model, the real boat will be 30 times that:
= 40 * 30
= 1,200 cm
A metre is equivalent to 100cm.
1,200 cm would therefore be:
= 1,200/100
= 12 metres
