the area, a, of a trapezoid is given by the formula a=1/2h(c+d), where h is the height and c and d are the lengths of the bases rearrange the formula so that the height h of the trapezoid can be determined given the area and the lengths of the bases enter your answer in the box

Answers

Answer:

this is algebra remember algebra rules and thing really hard

Step-by-step explanation:

The formula for the height of the trapezoid will be h = 2A/(c+ d).

What is surface area?

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

Given a trapezoid with side lengths c and d and perpendicular distance as h

So, the area formula will be

A = (1/2)h(c + d)

Multiply both sides by 2

2A = h (c + d)

Divide by c + d into both sides

2A/(c + d) = h

Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".

Look at the rectangle and the square:

A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 12 inches, and the width QR is labeled as 6 inches. The side LM of the square is labeled as 6 inches
Sam says that the length of diagonal SQ is two times the length of diagonal OM.

Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.

Answers

Answer:

False

Step-by-step explanation:

Let's consider the triangle SQR. We know it is right-angle because part of the rectangle PQRS. We can use the Pythagorean theorem:

[tex]SQ^{2} = RQ^{2} + SR^{2} \\SQ^{2} = 36 + 144 = 180\\SQ = \sqrt{180} = 13,4[/tex]

We can do the same for the square in which ON = 6 because it's a square:

[tex]OM^{2} = MN^{2} + ON^{2} \\OM^{2} = 36 + 36 = 72\\OM = \sqrt{72} = 8.5[/tex]

Now let's compare them:

8.5 X 2 = 17 so OM X 2 is not equal to SQ

The sentence is false.
