The area of a parallelogram is given by the formula A=bh the area of the parallelogram on the right is 126 sq units. Find its ba
Elden [556K]
From the diagram we have

Base = 4x+1
Height = x+1

Area = Base × Height
126 = (4x+1)(x+1) ⇒ Expand the double bracket
126 = 4x^{2}+5x+1 ⇒ Subtract 126 both sides
0 = 4x^{2}+5x-125 ⇒ Factorise the quadratic expression
0 = (x-5)(4x+25) ⇒ Equating each factor to zero

x-5=0                       4x+25=0
x=5                           x=- \frac{25}{4}

We need the positive value of x so we use x=5

Height = 5+1 = 6
Base = 4(5)+1 = 21

Generally PV of annuity with growth is mathematically represented as

where PV is present value

PV of annuity with growth X= (P/ (r-g)) * (1- ((1+g)/(1+r))^n)

     \frac{P}{\frac{8\%}{y12-0.2\%} } *(1-((1+0.2\%)/(1+8.5\%/12))^(^8^*^1^2^)^)=65000

    196.7213115P* 0.384791918=65000

     196.7213115P=65000/0.384791918

    196.7213115P=168922.4668

     P= 168922.4668/196.7213115

    P= 858.6892063

First\ monthly\ payment= $858.69
