Answer:

  1. <u>P = 122 | A = 930</u>
  2. <u>P = 116 | A = 616</u>
  3. <u>P = 128 | A = 1008</u>

<h3>Solve(perimeter) ➕</h3>
  1. 2 · (30 + 31) = 122
  2. 2 · (14 + 44) = 116
  3. 2 · (28 + 36) = 128

\sf Formula

<em>P</em> = 2 × (l + w)

<h3>Solve(area) ❎</h3>
  1. 31 · 30 = 930
  2. 44 · 14 = 616
  3. 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

The formula relating the forces is xd= y (L-d). What formula can you use to find the length of the lever?
labwork [276]
So assuming L=legnth

xd=y(L-d)
divide both sides by y
(xd)/y=L-d
add d to both sides
((xd)/y)+d=L

The sum of two numbers is 43 . The smaller number is 19 less than the larger number. What are the numbers?
Setler [38]
Let the smaller number be x and the larger number be y.
We can calculate this by using simultaneous equation, aka listing 2 equations out.
From given,
X + y = 43
Let this be equation no. 1
X + 19 = y
Let this number be equation 2.
We can do simultaneous equations either by substitute method or elimination. In this case I'm using substitute.
We can already obtain the value of y (in terms of x) in euqation no. 2, so all we gonna do is to put y into equation 1.
X + x + 19 = 43
Solve this by algebra.
2x = 43 - 19
X = 12
Now we know the exact value of x
Now substitute x = 12 into equation no. 2
12 + 19 = y
Y = 31
So the answer is 12 and 31
