Answer:

288 cm^2

Step-by-step explanation:

The diagonal of the square is 24 = 2 *12

We can use Pythagorean theorem to solve.

Let s= side length of the square

s^2 + s^2 = 24^2

2s^2 = 24^2

2s^2 =576

Divide each side by 2

2/2s^2 =576/2

s^2 = 288

Take the square root each side

sqrt(s^2) = sqrt(288)

s = 16.97056275

s = 16.97 cm

We want to find the area

A =s^2

A = 16.97 ^2

A = 288 cm^2

Answer:


Step-by-step explanation:

This is not a linear relationship, it doesn't have a set increase or uniform slope and it seems more like an exponential or quadratic curve to me when I graph it. As you can see you cant draw a straight line through the data points so it cannot be a linear relationship.

Harman [31]
Let height of house be x.

Oak tree = 120 + x

Also given,

Oak tree = 2.5x

120 + x = 2.5x

1.5x = 120

0.3x = 24

3x = 240

x = 80

Hence, the height of the house is 80 ft.
