Question

Can someone explain please

Answer 1

Answer:

Step-by-step explanation:

This might be familiar to you if you know about the pythagorean relationship in right triangle, aka pythagoras's theorem.

It states that, in a right triangle, the sum of the squares of the 2 shorter sides equals the square of the longest side, aka the hypotenuse.

Note that the triangle in this case is a right angled triangle, and all the surrounding shapes are squares.

So by the pythagorean relationship we have,

2^2 + 4^2 = c^2

4 + 16 = c^2

20 = c^2

c =  sq root 20 = 2 * sq root 5

Hope it helps and if it does, plzzz mark me brainliest ;-)

Answer 2

Answer:  4.472
