First, we must understand that to find the perimeter of an object you must add up the lengths of each side.

Some options are:

A square (4 sides) with sides of 4 units long.
4x4=16

A rectangle (4 sides) that is 6 units long and 2 units wide
6+2+6+2=16

An octagon (8 sides) with sides 2 units long
8x2=16

Jennifer places $500 into a savings account that is paying 1.5% annual interest. The interest is compounded monthly. How much mo

Anna11 [10]

Answer:

$522.99

Step-by-step explanation:

$FV = P (1 + \frac{r}{n} )^n^t$

Fv = total amount plus interest over the given period of time

P = Principal amount deposited i.e $500

r = interest given 1.5% i.e 0.015

n = period of time the principal remains deposited. In this case annually i.e 12 months

$FV = 500 ( 1 + \frac{0.015}{12} ) ^1^2^X^3$

$FV = 500 ( 1.04599)$

FV = $522.99

Answer:

$Area = 58 \ units^2$

Step-by-step explanation:

We can start by finding the third side of the triangle/the side of the square using the Pythagorean Theorem:

$a^2+b^2=c^2$

In this case the side length of the square would be represented by the variable "c" as it is the hypotenuse:

$3^2+7^2=c^2$

$9+49=c^2$

$c^2=58$

$c=\sqrt{58}$

Since the area of a square is the side length square then...

$Area =( \sqrt{58} )^2$

The square root and the squared cancel out giving us...

$Area = 58 \ units^2$
