Answer:
A = 21 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (b₁ + b₂ )
where h is the height between bases and b₁, b₂ are the parallel bases
Here h = 3, b₁ = 9, b₂ = 5 , then
A = × 3 × (9 + 5) = 1.5 × 14 = 21 cm²
Answer:
D
Step-by-step explanation:
6x^2 + 10x^2 = 16x^2
2x-x = x
-8 + 14 = 6
16x^2 + x + 6
