Answer:
84 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 5+9) * 12
A = 1/2 (14) * 12
A =84
The equation is for when you compound annually is

A=future amount
P=initial amount or principal
r=interest rate in decimal form
t=time in years
so
A=A
P=3500
r=7.5%=0.075
t=13


use your calculator
A=8961.4457
round to nearest dollar
A=$8961
that's how much the investment will be worth after 13 years
Proving that Triangle CDA is congruent to triangle CDB below:
- SSA ( angle one is equal to angle two and also side CD is on both side so it is equal, finally side BD is equal to AD because the line was bisected
<h3>Meaning of congruent triangle</h3>
Congruent triangles can be defined as triangles that have the same size and shape.
A congruent triangle, corresponding angles are equal also the corresponding sides are equal.
In conclusion, the proof that Triangle CDA is congruent to triangle CDB is given above
