A latter institution question and answer asked over students to express what they admit is the main important point for a student to do in order to accomplish success. From the numerous reactions, one that that stood out was practice. People who were successful do not become successful by being born. They work hard and determination their lives to succeeding. This is how you can reach your goals. These are some question and answer examples that you will be able to implement to further enhance your knowledge and gain insight that will help you to preserve your school studies.

## Question:

Justin sketched trapezoid BALI on a coordinate plane. BALI has vertices located at B(1,4), A(-2,0), L(7,0), and I (3,4). Which of the following is the area of BALI?

a) 21.32 square units

b) 22 square units

c) 32 square units

d) 47.97 square units

## Answer:

We shall first plot the points.

A(-2,0), B(1,4) , C(3,4), D(7,0)

After we plot the points we join the points.

We analyze that it is a trapezium.

Now counting the units we get

BC = b = 2 units

AD = a = 9 units

The height = BE = h = 4 units

The formula to find the area of trapezium is = 1/2 ×h ×(a+b)

Substituting the values of a, b & h we get

Area = 1/2 ×4 ×(2 + 9)

Area = 1/2 × 4 × 11 = 44/2 = 22 square units.

**Option B) is the right answer**

They would possibly hopefully help the student sort out the question by using the questions and answer examples. You can certainly then have a discussion with your classmate and continue the school learning by studying the question as a group.
