Answer is 9.5 First find DC by doing the Pythagorean theorem
BC is 3 BD is 5
So 3^2+ DC= 5^2
9+____=25
So DC is 4 cuz 4times 4=16

Now add AD+DC=AC

5+4=9

So BC is 3 the bottom AC is 9
3^2+9^2= 9+81=90 the sq rt of 90 is 9.5

30 points !!!! Find the area of a trapezoid, given the bases b1 = 14 mi and b2 = 25 mi and height h = 6 mi. 117 mi2 217 mi2 234

Deffense [45]

Answer:

117 mi²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h (b₁ + b₂), substitute values

= $\frac{1}2}$ × 6 × (14 + 25)

= 3 × 39

= 117 mi²
