The left side can be written as a square. We can take the square root, then subtract 1.

... (x +1)² = 17

... x +1 = ±√17

... x = -1 ±√17

The area of the triangle is 1560 m2 True False

ValentinkaMS [17]

Answer:

FALSE

Step-by-step explanation:

Area of triangle is given by formula :

$Area\ =\ \frac{1}{2}\left(base\right)\left(Altitude\right)$

From picture we see that Altitude = 60 m

Base = 52 + 71 = 123 m

Now plug these values into above formula:

$Area\ =\ \frac{1}{2}\left(123\right)\left(60\right)$

$Area\ =\ \frac{1}{2}\left(15129\right)$

$Area\ =\ \frac{15129}{2}$

$Area\ =\ 7564.5$

Which is different than given area 1560 m^2.

Hence answer is FALSE.
