What is the area of the trapezoid?
ExtremeBDS [4]
<h2>Answer:</h2>

42 square units

<h2>Step-by-step explanation:</h2>

For a better understanding, I add an EFGH Rectangle.

The area of EFGH Rectangle = p x l

The area of EFGH Rectangle = 10 x 8

The area of EFGH Rectangle = 80cm²

The area of BHA Triangle = 1/2 x a x t

The area of BHA Triangle = 1/2 x a x t

The area of BHA Triangle = 1/2 x 6 x 4

The area of BHA Triangle = 2 x 6

The area of BHA Triangle = 12cm²

The area of AGD Triangle = 1/2 x a x t

The area of AGD Triangle = 1/2 x 4 x 2

The area of AGD Triangle = 4cm²

The area of CFD Triangle = 1/2 x a x t

The area of CFD Triangle = 1/2 x 2 x 6

The area of CFD Triangle = 6cm²

The area of BEC Triangle = 1/2 x a x t

The area of BEC Triangle = 1/2 x 8 x 4

The area of BEC Triangle = 4 x 4

The area of BEC Triangle = 16cm²

The area of the trapezoid = EFGH Rectangle - (BHA Triangle + AGD Triangle + CFD Triangle + BEC Triangle)

The area of the trapezoid = 80 - (12 + 4 + 6 + 16)

The area of the trapezoid = 80 - 38

The area of the trapezoid = 42cm²

<h3>Conclusion :</h3>

The area of the trapezoid is <u>42 square units</u>

How to put 50,000,000 in standard form?
SVEN [57.7K]

Answer:

50,000,000 is in standard form.

Step-by-step explanation:

This is because standard form would be a written number. So, the non-standard form of 50,000,000 would be fifty million.

On a map, 2 1/2 cm represents 60 km. What is the actual distance between two cities that are 5 1/2 cm apart on the map?
lesya [120]

Answer:

They would be 132km apart

Step-by-step explanation:

In order to solve this we need to set up a proportion. To make that easier, let's first change the fractions into decimals.

2 1/2 = 2.5

5 1/2 = 5.5

Now we can put the scale in the right side fraction and the distance in the left.

2.5cm/60km = 5.5cm/xkm

Now cross multiply to solve

60 * 5.5 = 2.5 * x

330 = 2.5x

132 = x
