CAN SOMEONE PLEASE HELP?

The area of the figure is A. 216 cm².

Step-by-step explanation:

Step 1:

To calculate the value of the composite shape we first divide it into shapes that we know.

In this case, the composite figure consists of a rectangle and a triangle attached to it.

If we can calculate the individual areas of the two shapes we should be able to calculate the area of the composite shape.

Step 2:

The triangle has a base length of 8 cm and a height of 12 cm. The area of the triangle

The area of the triangle is 48 cm².

Step 3:

The area of a rectangle is the product of its length and its width.

The given rectangle has a length of 14 cm and a width of 12 cm.

The area of the rectangle

The area of the rectangle is 168 cm².

Step 4:

Now we calculate the area of the entire figure by adding the areas of the triangle and the rectangle.

Area of the figure

So the area of the figure is 216 cm² which is option A.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
