Answer:
Area = 7 square units
Perimeter = 14 units
Step-by-step explanation:
The shape is made up of 7 identical squares and, we are told the side length of each square is 1 unit.
==>Find area of the shape by calculating the area of 1 square, then multiply by the number of square used in the construction.
Thus, area of 1 square = s² = 1² = 1 square units.
Area of shape = 7 × 1 square units = 7 square units
==>Find the Perimeter of the shape by adding all the lengths of the boundary formed by the square to make up the shape.
(Check attachment to understand how we got the measurement of the boundary)
<em>The perimeter = 1 + 1 + 1 + ½ + ½ + 1 + 1 + 1½ + ½ + 1 + 1 + 4 = 14 units</em>

Our equation for the area of a rectangle is l x w = A (length times width equals area)
We know that l=w+20 so we can plug this into our equation.
It is now, (w+20) x w =800
We can then solve for w
w^2 +20w =800
We can subtract 800 on each side to get
w^2 +20w - 800 =0
We then factor to get
(w-20)(w+40)=0
This gives us w =20 and w = -40
Width cannot be negative so our width will be 20 feet
Since our length is 20 more than this, then our length will be 40feet
So the dimensions of the rectangle are 20 ft wide by 40 ft long
In order to answer this item, we must note that if the two angles are congruent then, they have the same measures. Therefore, we equate the given expressions,
<span> 4x – 25 = 2x + 5</span>
The value of x from the equation is 15. Substituting this value to any of the expression will give us an answer of 35. Thus, a measure of angle RQS is 35 degrees.

Answer:
9
Step-by-step explanation:
Given,
Total number of rooms = 162
One attendant is to clean 18 rooms per day.
Therefore if a full house is expected next Monday,
Number of attendant required to cover the day's cleaning task
= 162/18
= 9
Therefore, 9 guest room attendants will be needed to cover the day's cleaning tasks,
