Find the are of a parallelogram that has a base of 7 1/2 and a height of 5 2/7

Amiraneli [1.4K]

Use the formula for the area of a parallelogram:

$\sf A=bh$

Plug in what we know:

$\sf A=(7\dfrac{1}{2})(5\dfrac{2}{7})$

Convert both of them into improper fractions. We do this by multiplying the denominator to the whole number, adding it to the numerator, which becomes our new numerator, and we keep the denominator the same:

$\sf A=(\dfrac{15}{2})(\dfrac{37}{7})$

Now multiply the numerators and denominators together:

$\sf A=\dfrac{15}{2}\cdot\dfrac{37}{7}\rightarrow\dfrac{15\cdot 37}{2\cdot 7}\rightarrow\dfrac{555}{14}$

Convert it back into a mixed number. 14 goes into 555 thirty-nine times. 14 * 39 = 546. 555 - 546 = 9. So we have 39 wholes and 9 left over, or:

$\sf 39\dfrac{9}{14}$

So this is the area of the parallelogram.

Please Explain!! I need help plss

Nimfa-mama [501]

Answer:

See step by step

Step-by-step explanation:

For A. use any two factors that multiply to 100 that isn't 25 and 4.

For b Use one obtuse angle (angle over 90 degree) and two acute angles. Make sure they add up to 180.

For c Use any two values that add up to 52 since they didnt establish y as the midpoint.

For d. measure of angle 1 is 45 and measure of angle 2 is 45 degrees

Solve equation 8-3(p-4)=2p

LenKa [72]

Answer:

ok the answer is: p=-4

Step-by-step explanation:

First you distribute 3 times p-4 and get 8-3p+12=2p then you add 12 plus 8 and get 20 then you have 20-3p=2p you have to add 3p on both sides and you get 20= -5p you divide and get p= -4

Someone please help me I’m so confused!!!

QveST [7]

Answer:

number one. 186 $in^{2}$ number two. 36 $cm^{2}$

Step-by-step explanation:

FOR NUMBER ONE:

the area of a trapezoid formula is $\frac{a+b}{2} h$ where a and b are the bases and h is the height. so we have to add in the numbers into the formula

$\frac{12+15}{2} * 6\\$ = 81

and the paralellogram formula is b×h. where b is the base and h is height

15 × 7 = 105

so the area of the figure is 81 + 105 is 186 in^2

FOR NUMBER TWO:

the area of the square formula is $s^{2}$ . where s is the side

4^2 = 16

and for the paralellogram is b × h

4 × 5 = 20

so the area of the figure is 16 +20 = 36 in^2

hope this helps! ;)
