Thanh and her crew are building a stage in the shape of a trapezoid for an upcoming festival. the lengths of the parallel sides of the trapezoid are 14 ft and 24 ft. the height of the trapezoid is 12 ft. what is the area of the stage?

Step-by-step explanation:

Given: The lengths of the parallel sides of the trapezoid are 14 ft and 24 ft. The height of the trapezoid= 12 ft.

We know that area of trapezoid is given by :-

, where a and b are the parallel sides and h is the height of the trapezoid.

Now, the area of the trapezoid shaped stage is given by :-

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
