How do we find the breadth of square if perimeter and length is given

madreJ [45]

Answer:

A square has 4 sides of equal length, so if you have been given the length, this is also the breadth.

Therefore, the perimeter is 4 x side length.

For example, imagine a square with side length 3 cm. As all four side lengths are equal, the perimeter would be 4 x 3 cm = 12 cm

Beth will borrow $10,000 which earns 4% compound interest and she will repay that amount in 20 years. How much interest was earn

Serggg [28]

Answer:

$I=\$11,911.23$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the amount that she will repay

P is the amount borrowed

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=20\ years\\ P=\$10,000\\ r=0.04\\n=1$

substitute in the formula above

$A=10,000(1+\frac{0.04}{1})^{1*20}$

$A=10,000(1.04)^{20}$

$A=\$21,911.23$

Find out the interest

$I=A-P$

substitute the values

$I=\$21,911.23-\$10,000=\$11,911.23$

A 20-foot ladder leans up against the side of a building so that the foot of the ladder is 10 feet from the base of the building

harina [27]

Answer:

17.3

Step-by-step explanation:

To solve this equation, you need to use the pythagorean theorem which is:

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

a= length

b= height

c= hypotenuse

First, substitute in your values for the equation:

$10^2+b^{2} =20^{2}$

Then, use the squares in the equation:

$100+b^{2} =400$

Then, subtract 100 from both sides to isolate b:

$b^{2} =300$

Finally, square root both sides to get your answer:

$b=17.3205080757$

Then round to the nearest tenth which gives you 17.3.
