The perimeter is just adding all the sides together.
a.) 180 = 40 + 40 + x + x
180 = 80 + 2x Subtract 80 on both sides
100 = 2x Take 1/2 of 100 to get x
x= 50cm
b.) 1000 = 150 + 150 + x + x
1000 = 300 + 2x Subtract 300 on both sides
700 = 2x Take 1/2 of 700 to get x
x = 350
Given that 4 people would not <span>go to a park or a beach or a cottage.
Number of people that will </span><span>go to neither a park nor a cottage but will go to a beach = 5 - 4 = 1.
</span><span>Number of people that will <span>go to neither a beach nor a cottage but will go to a park = 9 - 4 = 5
</span></span>
<span>Number of people that will <span>go to neither a park nor a beach but will go to a cottage = 8 - 4 = 4
</span></span>
Number of people that will not go to a cottage but will go to a beach or a park = 12 - 5 - 1 = 6
Number of people that will not go to a beach but will go to a cottage or a park = 10 - 5 - 4 = 1
Number of people that will not go to a park but will go to a beach or a cottage = 12 - 4 - 1 = 7
Number of people <span>willing to go to all three places = 5
Therefore, total number of colleagues = 4 + 1 + 5 + 4 + 6 + 1 + 7 + 5 = 33

Step-by-step explanation:
The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
