Answer:
What is an inverse?
Recall that a number multiplied by its inverse equals 1. From basic arithmetic we know that:
The inverse of a number A is 1/A since A * 1/A = 1 (e.g. the inverse of 5 is 1/5)
All real numbers other than 0 have an inverse
Multiplying a number by the inverse of A is equivalent to dividing by A (e.g. 10/5 is the same as 10* 1/5)
What is a modular inverse?
In modular arithmetic we do not have a division operation. However, we do have modular inverses.
The modular inverse of A (mod C) is A^-1
(A * A^-1) ≡ 1 (mod C) or equivalently (A * A^-1) mod C = 1
Only the numbers coprime to C (numbers that share no prime factors with C) have a modular inverse (mod C)

Back of lot of the trapezoid = 175
Front of lot of the trapezoid = 185
Length of lot of the trapezoid = 100
<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>
Area of the trapezoid
- <em>[</em><em>On</em><em> </em><em>putting</em><em> </em><em>the</em><em> </em><em>values</em><em>]</em>
- <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>
= 360 × 50
- <em>[</em><em>On multiplying</em><em>]</em>
= 18000
<em><u>Hence</u></em><em><u>,</u></em>
We got the <em>T</em><em>otal Area </em><em>as</em><em> </em><em>180</em><em>0</em><em>0</em><em>.</em>

24/3=8
13+8=21
Here we have a problem of rates of work, where we want to find the rate at which two people would work together, so we can find the time it takes to complete a given job when these two work together..
We will find that they need to work for 6/5 hours to do the laundry together.
---------------------------------------
We know that:
- Muriel can do the laundry in 3 hours.
- Rea can do the laundry in 2 hours.
<em>Then we can define:</em>
- M = rate at which Muriel works = 1/3h
- R = rate at which Rea works = 1/2h
Where the rates are computed as the quotient between 1 (1 total laundry completed) and the amount of time it takes to do it.
If they work together, the rate just adds up, so we will have:
rate = (M + R) = 1/3h + 1/2h
Now we need to write that as a single fraction, so we get:
rate = 1/3h + 1/2h = 2/6h + 3/6h = 5/6h
Now we can write an equation of the form:
rate*time = 1
Where the 1 again, means "one complete laundry done".
Then we have:
(5/6h)*T = 1
T = (6/5)h
This means that they need to work for (6/5) hours to do the laundry together.
