Area of a Triangle = 0.5 x Base x Height 
 
Therefore the area of one mosaic triangle = 0.5 x 3 x 5 = 7.5

So the area of the whole mosaic is : 7.5 x 200 = 1500cm^2

solmaris [256]

Answer:

Javier's parents set aside $1500 when he was born

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question, we have that:

E = 1012.50, t = 15, I = 0.045

We have to find P. So

E = P*I*t

1012.50 = P*15*0.045

P = \frac{1012.50}{15*0.045}

P = 1500
