Answer:

12 square inches

Step-by-step explanation:

The area is given by the formula ...

A = 1/2bh

Here, the base is 6 inches and the height is given as 4 inches. Then the area is ...

A = (1/2)(6 in)(4 in) = 12 in²

The area of the triangle is 12 square inches.

<em>Comment on the problem</em>

Since you are given the base and height, we presume you are intended to use the formula above. You are also given all three side lengths. If you use the appropriate formula with those, you find the area is about 15.6 square inches. (The height of this triangle is actually closer to 5.2 inches.)

The figure represents a geometry that cannot exist. With the given base and height, the side lengths should be 5, not 6.

A triangle has an area of 900m2 . If a parallelogram has the same height and base as the triangle, what is the area of the paral

timama [110]

Answer:

1800 $m^{2}$ is the area of parallelogram.

Step-by-step explanation:

Given that:

Area of a triangle = 900 $m^{2}$

To find:

Area of a parallelogram which has same height and base as that of the given triangle.

Solution:

First of all, let us have a look at the formula for Area of a parallelogram:

$Area_{Par} = Base \times Height$ ...... (1)

So as to find the area of a parallelogram, we need to have the product of Base and Height of Parallelogram.

Now, let us have a look at the formula for area of a triangle:

$Area_{Tri} = \dfrac{1}{2} \times Base \times Height$

Given that height and base of triangle and parallelogram are equal to each other.

So,the product of base and height will also be equal to each other.

$900 = \dfrac{1}{2} \times Base \times Height\\\Rightarrow Base \times Height = 2 \times 900\\\Rightarrow Base \times Height = 1800\ m^2$

By equation (1):

<em>Area of parallelogram = 1800 </em> $m^{2}$ <em> </em>

What is 7√11√ in simplest radical form?<br> Enter your answer in the box.

Tpy6a [65]

Answer:

$\frac{\sqrt{77} }{11}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$ and

$\sqrt{a}$ × $\sqrt{a}$ = a

Given

$\frac{\sqrt{7} }{\sqrt{11} }$

To rationalise the denominator multiply numerator/ denominator by $\sqrt{11}$

$\frac{\sqrt{7} }{\sqrt{11} }$ × $\frac{\sqrt{11} }{\sqrt{11} }$

= $\frac{\sqrt{7(11)} }{\sqrt{11(11)} }$

= $\frac{\sqrt{77} }{11}$
