One side of a square is 11 ft. Tom found that the area of his square is 22. Is Tom correct? Explain why he is correct or incorre

guapka [62]

Answer:

Tom is incorrect.

Step-by-step explanation:

A square by definition implies that all sides of the square are the same measurements. In the case of finding the area, A = s². Tom, however, solved it as A = 2s.

In this case:

Area of square = s² = 11² = 121 ft²

121 ft² is the correct measurement.

Serhud [2]

Answer:

x=19

Step-by-step explanation:

First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:

$15^{2} +x^{2}=24^{2}$

Then you square the numbers that you currently have:

$225+x^{2}=576$

Then subtract 225 from both sides to isolate the x:

$x^{2} =576-225$

This gives you the equation:

$x^{2} =351$

Then take the square root of both sides which gives you:

$x=18.7349939952$

Then round to the nearest whole number which gives you x=19
