Well, you could tackle the rectangle first; it doesn't really matter what order you go in, as long as you get the final answer.
1) I'll start with the rectangle. Area=base x height, so 10*4=40
2) The top triangle will go next. Area=(base x height) divided by two. 4*10=40
40/2=20
3) Bottom triangle. 3*10=30
30/2=15
4) Add all areas together: 40+20+15=75

The total area is 75cm².
Hope this helps!

Find the principal. SHOW ALL WORK to receive FULL CREDIT.
s344n2d4d5 [400]

Answer:

300

Step-by-step explanation:

I = interest earned

P = Principal

R = interest rate

T = Months

plug in all the numbers which would be...

45 = P x 0.03 x 5 *Note that 0.03 is 3% in decimal form

0.03 x 5 = 0.15

45 = P x 0.15

to make the P by itself you have to divide 0.15 to both sides

45/0.15 = 300

P = 300
