Question

Plz help ASAP! I will mark brainliest if correct

Answer 1

A = L^2
A = L^2 = 2^2 + 4^2 (Pythagorean’s theorem)
A = L^2 = 20
Therefore the area of the square is 20 units square.

Answer 2

Answer:

The answer is 20

Step-by-step explanation:

To find the hypotenuse, you use the pythagorean theorem ($A^{2}+ B^{2}= C^{2}$).

We are given A and B so you insert.

$2^{2}+ 4^{2} =C^{2}$

4+16=$C^{2}$

$C^{2}$=20

Now you take the square root of C and since it is even, I will leave it in a square root sign.

C=$\sqrt{20}$

C is one side of a square and since all sides are the same, we don't have to find anymore. Now we insert C into the formula for finding the area of a square.

A=$C^{2}$

A=$\sqrt{20} ^{2}$

A=20
