Ok start off by finding the base first and the equation of finding the area of the square is A=bh
A=11 x 11= 121 cm^2

Next find the area of one triangle and the equation is A=1/2bh
A=1/2(11)(10)
A=55 cm^2

Multiply the area of one triangle by 4 since there are four triangles and it should equal to 220 cm^2. You then add this to the base and the final answer should be 341 cm^2.

I hope this helps

Answer:

341 cm²

Step-by-step explanation:

A=11 x 11= 121 cm²

A=1/2(11)(10)

A=55 cm²

Multiply the area of one triangle by 4 since there are four triangles.

=220 cm²

220+121=341cm²

Find the area of a trapezoid if the altitude is 6 inches and the median is 8 inches. (Hint: Recall that the median of a

zlopas [31]

Answer:

48 sq. units

Step-by-step explanation:

The area of a trapezoid is given by half sum of the bases multiplied by the height

$=\frac{1}{2} (a+b)h$

where a and b are the two parallel sides of the trapezoid and h is the height or amplitude of the trapezoid

But you are aware that, the median of a trapezoid is equal to half the sum of the bases, thus the first part of the formulae is covered by the median

$Median=\frac{1}{2} (a+b)$

Hence area, A, of a trapezoid is simplified to product of median and amplitude

$A=amplitude*median\\\\A=6*8=48sq.units$

Match the reasons with the statements in the proof.

Len [333]

Observe the given figure.

Given: $m \angle 1 = m \angle 3, m \angle 2 = m \angle 3$

To prove: $l \parallel m$

Statement

1. $m \angle 1 = m \angle 3, m \angle 2 = m \angle 3$

Reason: Given

2. $m \angle 1 = m \angle 2$

Reason: Substitution

3. $\angle 1,\angle 2$ are alternate interior angles.

Reason: Definition of alternate interior angles

4. $l \parallel m$

Reason: If alternate interior angles are equal, then the lines are parallel.

HELP....(drag and drop question)

Nonamiya [84]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the point $(-8,\ 2)$ and the slope $m=\dfrac{1}{2}$ .

Substitute:

$y-2=\dfrac{1}{2}(x-(-8))\\\\\boxed{y-2=\dfrac{1}{2}(x+8)}$
