First You do length times width which would be 54 and then divide that by 3 and you would get your answer.
54÷(9×6)
3x²<span> + 2x + 7 = 0
D = b</span>² - 4ac = 2² - 4*3*7 = 4 - 84 = -80
D < 0 ⇒ <span>No real solutions</span>
D, because if you distribute 4(3+2) it equals= 4x3
= 12
4x2
=8
and there’s an addition sign so you will add the remaining numbers 12+8
Answer:
104.5 meters square
Step-by-step explanation:
The area of a trapezoid is found using the formula A = 1/2 (a + b)h. Substitute a = 8, b = 11 and h = 12.
The area is A = 1/2(8+11)*12.
A = 1/2 (19)*12 = 104.5
