Answer:
40units²
Step-by-step explanation:
find the shapes you know the formula of. There's two shapes a rectangle and a trapezoid.
do the formula for rectangle
A = bh
A = 8×2
A = 16
Now the formula for Trapezoid
A = 1/2h(b+b)
A = 1/2×4(4+8)
A = 1/2×4(12)
A = 1/2(48)
A = 24
16+24 = 40
The second choice is correct because the opposite angles along the horizontal transversal are congruent.
Answer:
16.3 feet (to the nearest tenth)
Step-by-step explanation:
Use Pythagoras theorem
Length = sqrt(3^2+16^2) = sqrt(9+256) = sqrt(265) = 16.3 ft.
