Answer:
1350
units²
Step-by-step explanation:
The regular hexagon consists of 6 equiangular triangles
The area (A) of a equilateral triangle is calculated as
A =
( s is the side length )
Here s = 30 , then
A =
=
= 225
units²
Thus the area of the regular hexagon is
area = 6 × 225
= 1350
units² ← exact value
≈ 2338.3 units² ( to 1 dec. place )

(2b^2+7b^2+b)+(2b^2-4b-12)
(9b^2+b)+(2b^2-4b-12)
9b^2+b+2b^2-4b-12
11b^2+b-4b-12
11b^2-3b-12
