Find the PERIMETER and AREA of each figure below

Oduvanchick [21]

Answer:

22)

$2(length+breadth+h)$

$2(5a^2b^2+3ab^2)$

$Perimeter: 2ab^2(5a^2+31)$

$Area:-$

$5a^2b^4 *3ab^2$

$A=15a^2b^6$

-----------

23)

$perimeter:-$

$4m^2+3mn^2+7mn$

$4m^2+10mn^2$

$answer: 2m(2m+5n^2)$

$Area:-$

$\frac{1}{2}* base* height$

$1/2*3mn^2*4m^2$

$6mx^{2+1}n^2$

$A=6m^3n^2$

----------

24)

$1/2*b*h$

$1/2x^24m^2*8mn$

$A=16m^3n$

----------

25)

$1/2*(7a^2b+11a^2b)*3ab$

$1/2*18a^2b*3ab$

$9a^2b*3ab$

$A=27 a^3b^2$

------------

26)

$A= 9\pi (x^3y)^2$

∴To calculate the perimeter , add the length of its sides.

∴To calculate the area, multiply its height by its width.

hope it helps...

have a great day!!

Of the 36 students in the environmental club, 15 or boys and 21 are girls. The president of the club wants to add more boys so t

schepotkina [342]

Because 50% of something means half (because 100-50=50), he would have to make the number of girls and boys equal. Since there are 21 girls, he has to make it so there are also 21 boys.
So, if we know that 21-15=6, this means he would have to add 6 boys to the club if he wants the girls and boys equal.

What is the slope of a line perpendicular to the line whose equation is 6x+2y=−32. Fully simplify your answer.

Reika [66]

The slope of the line that is perpendicular to 6x + 2y = -32 is: 1/3.

<h3>What is the Slope of Perpendicular Lines?</h3>

The slope of two lines that are perpendicular to each other will always have a product that is equal to -1, which means that their slopes are negative reciprocals to each other.

Rewrite 6x + 2y = -32 in slope-intercept form:

2y = -6x - 32

2y/2 = -6x/2 - 32/2

y = -3x - 16

The slope is -3. Negative reciprocal of -3 is 1/3.

Therefore, the slope of the perpendicular line would be: 1/3.
