the formula for simple interest is i=prt, where i is the interest, p is the principal, r is the interest rate, and t is time (in years). solve the formula for p. then use the formula to determine the principal for an account with a 2% interest rate that earned $300 in simple interest over the course of 8 years.

Replace the values for the letters in the given equation and solve for the missing letter:

I = Prt

Solve the equation for P by dividing both sides by rt:

P = I/rt

I = 300

r = 2% = 0.02

t = 8

O = 300/(0.02*8)

P = 300/0.16

P = $1,875

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
