The given triangles are congruent by :
because they have Two Angles and a side between them equal to the corresponding Angles and side of the another triangle.
Split it up into 3 separate shapes.
Rectangle 1 = 15 x 3 = 45
Rectangle 2 = 3 x 5 = 15
Triangle = 1/2 x 5 x 3 = 7.5
Total area = 45 + 15 + 7.5 = 67.5 cm²

Answer:
20 packages
Step-by-step explanation:
the school needs 1800 notebooks, since the notebooks come in packages of 90 each. there will be a total of 20 packages.
formula
1800/90
= 20
P is the principal amount, $5200.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 9....year(s) time periods.
So, t is 9....year time periods.
To find the simple interest, we multiply 5200 × 0.06 × 9 to get that:
The interest is: $2808.00
