The area of a parallelogram is  so the answer would be .

Find the area of the given parallelogram:

To find the area of a parallelogram, simply do the following:

Where b is the base, and h is the height. Note that the height is the length of the perpendicular line connecting both bases. In this case, our height is 12mi and our base is 144 miles.

Find the area of the given parallelogram:

To find the area of a parallelogram, simply use the following formula for area of a parallelogram:

Where b is the base, and h is the height. Note that the height is the length of the perpendicular line connecting both bases. In this case, our height is 12 mi and our base is 144 mi.

First, we must find the missing lengths. Because we know that the length going horizontally across on the bottom is 6 cm and 8 cm, that must mean that the length going across at the top must also equal this sum. 

So, the length of the top must equal

6 + 8 =

14.

We are given one value of the length on the top, 4. To find the missing horizontal length on the top, we must subtract 4 from 14.

14 – 4 = 10.

In order to find the other missing length, we must observe that the greatest vertical length of this figure is 12 cm. Because we are given 4 cm and 5 cm, we must subtract 4 and 5 from 12 to find the other missing length.

12 – 4 – 5 =

3.

Now, let's divide this enclosed region in three separate rectangles.

The rectangle at the top has a length of 4 cm and width of 3 cm.

The middle rectangle has a length of

10 + 4 =

14 cm

and a width of 5 cm. 

The bottom rectangle has a length of 8 cm and width of 4 cm.

If the formula for the area of a rectangle is length x width, we must now calculate the individual areas of each rectangle and add them up.

Area of top rectangle

4 x 3 = 12cm²

Area of middle rectangle

14 x 5 = 70cm²

Area of bottom rectangle

8 x 4 = 32cm²

12cm² + 32cm² + 70cm² =

114cm² 

The answer is 4 feet, because

and a rectangle must have 4 sides, with 2 sides of one length and 2 sides of another.

feet

making the other side 4 feet,

In order to determine how much material Bailey needs, we must first find the area of space she needs to cover. Since Bailey would like the quilt to be an extra foot on each side, we must add  feet to both the length and width.

Width 

Length

Now we apply the formula for the area of a rectangle, which is .

Multiply the length by the width to get the area of the rectangle:

The area of the rectangle is 198 square inches.

To find the area, simply multiply the sides of the rectangle. The only sides which add up to are:

Since 1 meter = 100 centimeters, multiply each dimension by 100 to convert meters to centimeters. This makes the dimensions 200 centimeters by 500 centimeters. 

Use the area formula, substituting :

The area of a rectangle can be calculated by multiplying the length by the width.
