Just replace a with 4 and b with 2 and your equation looks like
3.14 (4×2+4×2)
solve within the parenthesis first
3.14 (8+8)
3.14 (16) =50.24
Answer:
D
Step-by-step explanation:
Recall that the area of a triangle is given by:

In this case, the base is <em>x</em> and the height is <em>y</em>. Hence:

We can write the following ratios:

Solve for <em>x</em> and <em>y</em>:

Substitute:

And simplify. Hence:

In conclusion, our answer is D.

Answer:
9 years.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
t = 267.57 / ( 991 × 0.03 ) = 9
t = 9 years
The time required to
accumulate simple interest of $ 267.57
from a principal of $ 991.00
at an interest rate of 3% per year
is 9 years.
