the hint tells you s is sqrt(a)

the question tells you a = 570025

so side = sqrt(570025)

plug that into your calculator to get:

755 feet

21) Each side is 755 in
To do this all you'll need to do is find the root of 570,025, which is 755

22) Each side is 25 in
Again, you'll need to find the square root of 625, which is 25

The area of the house is the amount of space on the house.

The length of the addition is x + 20
The area of the original house is $x^2 + 30x + 200$

<h3>The length of the addition</h3>

The area of the addition is given as:

$Area = x^2 + 10x - 200$

Expand

$Area = x^2 + 20x - 10x - 200$

Factorize

$Area = x(x + 20) - 10(x + 20)$

Factor out x + 20

$Area = (x -10)(x + 20)$

The width of the addition is x - 10.

Hence, the length of the addition is x + 20

<h3>The area of the original house</h3>

The dimension of the original house is

x + 20 by x + 10

So, the area is:

$Area =(x + 20)(x + 10)$

Expand

$Area =x^2 + 20x + 10x + 200$

This gives

$Area =x^2 + 30x + 200$

Hence, the area of the original house is $x^2 + 30x + 200$

2. What is the surface area of the triangular prism below?

grandymaker [24]

2 x Area of the triangular ends.
= 2 x ( 1/2 bh)
= 2 x (1/2 x 6.8 x 5.1)

2 x Area of rectangular sides
= 2 x lw
2 x (6.1 x 13)

Area of bottom
= lw
= 6.8 x 13

Now add all three results together for the surface area.
