Answer:
424 cm²
Step-by-step explanation:
The figure is composed of a square and a trapezium on top
A of square = 18² = 324 cm²
A of trapezium =
h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 8, b₁ = 18 and b₂ = 7 , then
A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²
Area of hexagonal park = 324 + 100 = 424 cm²
The answer for 2 is 192. The answer for 4 is 672.

if your calculator is in Degree mode, you'll get the angle in degrees, if in Radian mode, you'll get radians get taking the inverse sine, so you know
Answer:
C
You have to check which of numbers is the lowest.
Cheers :D
If n is the first of these integers, then the other three are n + 1, n + 2, and n + 3. Then
n + (n + 1) + (n + 2) + (n + 3) = 114
4n + 6 = 114
4n = 108
n = 27
So the four numbers are 27, 28, 29, and 30.
