Answer:
A = 70 mm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 10, b₁ = 10, b₂ = 4 , then
A = × 10 × (10 + 4) = 5 × 14 = 70 mm²
Answer:
9x^9-18
Step-by-step explanation:
It would be 10/9
Use the keep, change, flip rule to solve
5*2=10 which will be in top
And 9*1=9 which will be at the bottom
