How do you Calculate the area of a missing square.

Amiraneli [1.4K]

Answer: Option D

Step-by-step explanation:

Hey there!

Here; Looking at it we can state that it is a Right angled triangle.

And must use the Pythagoras relation if the triangle is a Right angled triangle.

So, let's work on it.

Let ABC be a triangle.

Taking reference angle as C, we get;

perpendicular= 3m

Hypotenuse= 7m

Base = xm

Now;

${h}^{2} = {p}^{2} + {b}^{2}$

$or \: b = \sqrt{ {h}^{2} - {p}^{2} }$

Put all values.

$b = \sqrt{ {7}^{2} - {3}^{2} }$

Simplify to get answer.

$b = \sqrt{49 - 9}$

$b = \sqrt{40}$

Therefore, X= 6.3m.

Hope it helps...
