I’m pretty sure surface area is all the sides multiples then added
I’m going to assume the length is 10, width is 4, and height is 3
You would find the base of the rectangle which is the same as the top and that would be 80 (because 10 multiples by 4 for the base and top)
Then the ends which is 3x4= 12 and you have to sides so the total is 24
And lastly the sides which is 10x3= 30 and you have 2 sides so it’s really 60
In total you have 60+24+80= 164cm

Item 9 Find the annual interest rate. I=$562.50, P=$1500, t=5 yearsI=$562.50, P=$1500, t=5 years The annual interest rate is %.

Anton [14]

Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%

Hope it helps:-)
