Answer:

12.4

Step-by-step explanation:

We need to use Pythagoras Theorem.

It says the sum of the legs squared is equal to the square of the Hypotenuse

{h}^{2}  =  {3}^{2}  +  {12}^{2}

Simplify the exponents

{h}^{2}  =  9 + 144

Add on the right

{h}^{2}  = 153

Take square root

h =  \sqrt{153}

h = 12.4

Answer:

600.4 cm^2

Step-by-step explanation:

first we should find the base of samller triangle

hypotenuse = 35 cm

one side = 30 cm  whereas other has be be find

using pythagoras theorem

a^2 + b^2 = c^2

30^2 + b^2 = 35^2

900 + b^2 = 1225

b^2 = 1225 - 900

b^2 = 325

b = \sqrt{325}

b = 5\sqrt{13}

area of big triangle

base = 22 + 5\sqrt{13}

area of a triangle = base * height / 2

= 30 (22 + 5\sqrt{13} ) /2

=30*22 + 30*5\sqrt{13} / 2

=660 + 540.83 / 2

=1200.83 / 2

=600.415

=600.4 cm^2
