Ответ:
a = 40
b = 60
h = 24
Let's plug them in and solve.
A = a + b / 2(h)
A = 40 + 60 / 2(24
A = 100 / 2(24)
A = 50(24)
A = 1200
Remember we have to double the area of the trapezoid to get the area of the whole hexagon.
1200 × 2 = 2400
The area of the hexagon is 2,400 in².
Ответ:
d = √( (x₂ -x₁)² + (y₂ - y₁)²)
x₁ = -2, y₁ = 4, x₂ = 0, y₂ = -6
d = √( (x₂ -x₁)² + (y₂ - y₁)²)
d = √( (0 - -2)² + (-6 - 4)²)
d = √( (0 + 2)² + (-10)²)
d = √( (2)² + (-10)²)
d = √(4 + 100)
d = √104 Use a calculator
d ≈ 10.1980
d ≈ 10.20 units to the nearest hundredth.
