Answer 1

Step-by-step explanation:

Let:

AB (One side) = 4.5 cm

AC (Hypotenuse) = 20.5cm

BC (Third side) = ?

Using Pythagoras Theorem:

$AC^{2}=AB^{2} + BC^{2} \\BC^{2} = AC^{2} - AB^{2} \\BC^{2} = 20.5^2 - 4.5^2\\BC^{2} = 400\\BC = \sqrt{400} \\BC = 20cm$

Now Area of Right Triangle:

⇒ $Area = \sqrt{s}(s-a) (s-b) (s-c)$

⇒ $s = semiperimeter = \frac{a+b+c}{2}$

$s = \frac{4.5+20.5+20}{2} \\s = 40cm$

Now:

$\sqrt{45} (45-4.5)(45-20.5)(45-20)\\\sqrt{45} (40.5)(24.5)(25)\\\sqrt{45} (992.25)(25)\\\sqrt{45} (24,806.25)$

Answer 2

hiii Santa siso your answer got deleted T_T

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
