Answer:

b = 3 units

Step-by-step explanation:

Area of a parallelogram = base × height

Thus,

Area = 21 units²

base = b

height = 7

Plug in the value into the formula

Thus:

21 = b × 7

Divide both sides by 7

21/7 = b

3 = b

b = 3 units

Hi there
The formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
So we need to find the monthly payment pmt
Pmt=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 205000
R interest rate 0.056
K compounded monthly 12
N time 30

PMT=205,000÷((1−(1+0.056÷12)^(
−12×30))÷(0.056÷12))
=1,176.86...answer

Hope it helps
