Question

How do you Calculate the area of a missing square.

Answer 1

Answer: Option D

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 = √(49 - 9)`

`b = √(</u><u>4</u><u>0</u><u>)</u><u>`

Therefore, X= 6.3m.

Hope it helps...
