Question

What is the value of X​

Answer 1

Answer:

Option D is correct answer.

Step-by-step explanation:

For the area of Trapezoid we apply The formula

$\frac{1}{2}$ sum of parallel  sides X distance between them

Here in the question we have area = 98 square units

parallel sides are 20 units and 8 units ,Plugging them in the above formula

Let d be the distance between them

98=$\frac{1}{2}$ [ 8+20]  X d

98=14 X d

d= $\frac{98}{14}$

d = 7 units

Answer 2

Answer:

x = 7 units

Step-by-step explanation:

The area of the trapezoid is

A = 1/2 (b1+b2) *h

where b1 and b2 are the top and bottom and h is the height

Substituting what we know

 98 =1/2 (20 +8) *x

Combine like terms

98 = 1/2 (28)x

98 = 14x

Divide by 14 on each side

98/14 = 14x/14

7 =x
