Answer:
80 m²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (a + b)
where h is the perpendicular height between bases and a, b are the bases
Here h = 8, a = 14 and b = 6, thus
A =
× 8 × (14 + 6) = 4 × 20 = 80 m²
A: 7x+y=8 is the right answer, because if we move 7x to the other side we get: y=-7x+8
If you multiply 3 and 3 and 3
