Step-by-step explanation:
20÷1.5 since there is not X
Equation:
3x+10 = 45+10 = 55
The answer is 55 because this is a isosceles triangle.
If you want the area of the entire trapeziod.
The formula for area of a trapeziod is:
1/2h(b₁+b₂)
So the equation applied to the trapeziod is:
2.5(20+12)
20+12 is 32. 32 multiplied by 2.5 is 80.
