➥ The base of a parallelogram is thrice its height. If the area is 897 sq.cm. Find the base and height of the parallelogram.

IgorC [24]

Answer:

The height of parallelogram is 51.87 cm

Step-by-step explanation:

Let The height of a parallelogram = a cm

Then

The base of a parallelogram = 3a cm

So by the given condition

3a×a = 897

3a^2 = 897

a^2 = 897/3

a^2 = 299

a = 17.29

So the height of parallelogram = 3×17.29= 51.87 cm

Answer:

A = 119 units²

Step-by-step explanation:

side of square is (12√2)sin45 = 12

The portion of the diagonal that is NOT octagon is

12√2 - 12

There are four corner triangles. The sum of their areas is

(12√2 - 12)²

Area of the octagon is area of the square minus four corner triangle areas.

A = 12² - (12√2 - 12)²

A = 119.2935...

Answer:

Option B.

Step-by-step explanation:

The given expression is

$\dfrac{10x^2-32}{4}$

We need to find the simplified form of given expression.

Taking out GCF from the numerator.

$\dfrac{2(5x^2-16)}{4}$

Cancel out common factors.

$\dfrac{5x^2-16}{2}$

The expression $\dfrac{5x^2-16}{2}$ is the simplified form of given expression.

Therefore, the correct option is B.
