Answer:
area of the compostie figure = 34 squre units
Step-by-step explanation:
To find the area of this composite figure , first find the area of the trapezoid
then we subtract the area of rectangle (white part of the figure at the bottom)
Area of the trapezoid = (base1+base2)/2 times height
base 1= 10
base 2=6, height = 5
Area of a trapezoid = = 40
Area of the rectangle = length * width
= 3*2= 6
Now area of the compostie figure = 40 - 6= 34 squre units

Answer: Simple interest rate = 3%.
Step-by-step explanation: We are given invested amount = $5000.
Number of years of investment = 4 years.
Interest earned = $600.
Simple interest formula.
I = P R T.
Where I is the earned interest, P is the invested amount , R is the rate of interest and T is the time in years.
Plugging values in formula, we get
600 = 5000 × R × 4
600 = 20000R.
Dividing both sides by 20000, we get
0.03 = R.
Multiplying by 100 to convert it in percentage, we get
0.03 × 100 = R
R = 3 %.
