$S_1 = \frac{a+b}{2}h = \frac{7+9}{2}*5=\frac{18*5}{2}= 9 * 5 = 45~m^2$

$S_\triangle = \frac{ab}{2} = \frac{5*9}{2} = \frac{45}{2} = 22,5~m^2$

$S = S_1 + S_\triangle = 45 + 22,5 = 67,5~m^2$

Answer: 67,5 m².

Triangle UVW is formed by the three squares G, H, and I:

Serjik [45]

The phytagorean theorem states a^2 + b^2 = c^2 And so your answer is C. (UV)^2+(VW)^2=(UW)^2, because 81+144=225

Since they are squares, the length of one sides square is equal to the area. UV, VW, and UW are all sides on a square. If you square them, you get their area, and then if you add the areas it will prove the phytagorean theorem correct.
