The first thing we should know is the area of the triangular base.
Triangular base area:
A1 = root (s * (s-a) * (s-b) * (s-c))
Where, s is the semi-meter of the triangle:
s = (a + b + c) / 2
a, b, c: sides of the triangle.
Substituting:
s = (2 + 3 + 4) /2=4.5
A1 = root (4.5 * (4.5-2) * (4.5-3) * (4.5-4))
A1 = 2.90
Then, you must know the area of each rectangle associated with each side of the triangular base.
Rectangle area 1:
Ar1 = (a) * (l)
Ar1 = (2) * (7)
Ar1 = 14
Rectangular area 2:
Ar2 = (b) * (l)
Ar2 = (3) * (7)
Ar2 = 21
Rectangular area 3:
Ar3 = (a) * (l)
Ar3 = (4) * (7)
Ar3 = 28
Finally the surface area is:
A = Ar1 + Ar2 + Ar3 + 2 * A1
A = (14) + (21) + (28) + 2 * (2.90)
A = 68.8 in ^ 2
answer:
<span> the surface area of the box of chocolates is
</span> A = 68.8 in ^ 2

Savings account A and savings account B both offer APRs of 5%, but savings account A compounds interest annually, while savings

shepuryov [24]

<h2>Answer:</h2>

Account B will yield more.

<h2>Step-by-step explanation:</h2>

Savings account A and savings account B both offer APRs of 5%

But savings account A compounds interest annually, while savings account B compounds interest monthly.

Lets check which account will yield more :

<h2>Account A.</h2>

Lets take p = 10,000

r = 5% or 0.05

n = 1

t = 1

Compound interest formula is :

$p(1+\frac{r}{n})^{nt}$

Substituting values in formula;

$10000(1+\frac{0.05}{1})^{1}$

= $10500

<h2>Account B:</h2>

Lets take p = 10,000

r = 5% or 0.05

n = 12

t = 1

Compound interest formula is :

$p(1+\frac{r}{n})^{nt}$

Substituting values in formula;

$10000(1+\frac{0.05}{12})^{12}$

= $10510

We can see that account B gives more yield as compared to account A. When an account is compounded monthly, we earn interest on interest. This is why we yield more.

Therefore, account B will yield more.
