a = 10 cm, b = 15 cm, and c = 5 cm
A.
250 cm2
B.
175 cm2
C.
800 cm2
D.
200 cm2
Answers
The area of the trapezium is 175 cm².
Option B is the correct answer.
What is a trapezium?It is a quadrilateral that has one pair of parallel sides and a height.
The area is calculated as 1/2 x the sum of the parallel sides x height.
Examples:
Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.
Area = 1/2 x (3 + 4) x 5
Area = 1/2 x 7 x 5
Area = 35/2 = 17.5 cm^2
We have,
Parallel sides are b and (c + b).
b = 15 cm
c + b = 5 + 15 = 20 cm
Height = a = 10 cm
Now,
The area of the trapezium.
= 1/2 x (sum of the parallel sides) x height
= 1/2 x (15 + 20) x 10
= 1/2 x 35 x 10
= 35 x 5
= 175 cm²
Thus,
The area of the trapezium is 175 cm².

An object’s height is measured in centimeters and in inches. Two rulers, one showing inches, the other showing centimeters. The rulers are aligned at zero. An arrow extends from the one inch mark on the first ruler toward the equivalent length on the other ruler, with the caption, one inch equals two and fifty-four hundredths centimeters. Write an equation that relates the number of centimeters c to the number of inches i. Determine the height in centimeters of a chair that is 32 inches tall. Enter the correct answers in the boxes.
Answers
If an object’s height is measured in centimeters and in inches. the height of the chair in centimeters is 81.28 cm.
How to find the height?We know that one inch is equivalent to two and fifty-four hundredths centimeters. We can write this as:
1 inch = 2.54 centimeters
To find the equation that relates the number of centimeters c to the number of inches i, we can use this conversion factor:
c = 2.54i
This equation tells us that the number of centimeters is equal to 2.54 times the number of inches.
To find the height in centimeters of a chair that is 32 inches tall, we can plug in i = 32 into the equation above:
c = 2.54i
c = 2.54(32)
c = 81.28
Therefore, the height of the chair in centimeters is 81.28 cm.

Step-by-step explanation:
The inaccuracy in the histogram was discovered by the owner would be:
55-59
60-64
Data TableThe inaccuracy in the number of new clients due to the inapt portrayal of the data between intervals 55-59 and between 60 and 64.
They show the number of new clients as 5 and 6 in these intervals which is incorrect and hence, the histogram becomes wrong.
The actual frequency in these intervals is quite lesser as provided by the data and hence, the shown data is invalid.
Thus, the above responses are correct.
