Answer:

<u>P = 122 | A = 930</u>
<u>P = 116 | A = 616</u>
<u>P = 128 | A = 1008</u>

<h3>Solve(perimeter) ➕</h3>

2 · (30 + 31) = 122
2 · (14 + 44) = 116
2 · (28 + 36) = 128

$\sf Formula$

<em>P</em> = 2 × ( $l$ + $w$ )

<h3>Solve(area) ❎</h3>

31 · 30 = 930
44 · 14 = 616
36 · 28 = 1008

$\sf Formula$

A = $w$ × $l$

Answer:
(a)

Area: 930 meters(m)

Perimeter: 122 meters(m)

(b)

Area: 616 centimeters(cm)

Perimeter: 116 centimeters(cm)

(c)

Area: 1008 millimeters(mm)

Perimeter: 128 millimeters(mm)

Explanation:

Area = length x width

Perimeter = length+width+length+width

Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008

Perimeter for (a) is 31+30+31+30=122

Perimeter for (b) is 44+14+44+14=116

Perimeter for (c) is 36+28+36+28=128

What is the simplified form of 30 times x to the sixth power over 14 times y to the fifth power times the fraction 7 times y-squ

Sonbull [250]

If we convert the given in its mathematical form, we have,

(30x⁶/14y⁵)(7y²/6x⁴)
It can be observed that the numerator of the first and the denominator of the second have a common factor of 6x⁴. Also, the denominator of the first and the numerator of the second expression have a common factor of 7y².

((6x⁴)(5x²)/(7y²)(2y³))(7y²/6x⁴)

Cancellation of the common terms will give us an answer of,

<em>5x²/2y³

</em><em />Therefore, the simplified version of the involved operation is 5x²/2y³. <em>
