The square in the middle has an
1 answer:
Answer:
4 square units
Step-by-step explanation:
Given that the square we have in the middle of the diagram has an area of 1 square unit, to find the area of the entire angle, all we need to do is decompose and reaarange the other shapes where necessary to form the square in the middle.
See the attachment below showing how we can break and arrange the other shapes to derive their area.
Thus, the 2 smaller triangles can be reaaranged to form the middle square. Since the middle square = 1 unit², each smaller triangle = ½ unit².
The other two medium triangles can be decomposed into 2 smaller triangles, which will give us the middle square.
Therefore, the area if the entire rectangle is:
Middle square = 1 unit²
Two smaller triangles = 1 middle square = 1 unit²
2 medium triangles = 4 smaller triangles = 2 middle squares = 2 units
Area of the entire rectangle = 1 + 1 + 2 = 4 square units

To complete the table we must carefully observe the keypad, we will notice that each number is equivalent to 3 letters of the alphabet except the numbers 7 and 9 which have 4 letters each.
<h3>How does the keypad work?</h3>Previously, cell phone keypad had a different layout than today. The numbers were related to the letters of the alphabet and the number key was pressed according to the letters that were related.
For example, if you wanted to type the letter B, you would have to press the number 2 key twice.
The relationship of numbers and letters was distributed as follows:
- It had no letters.
- A, B and C.
- D, E and F.
- G, H and I.
- J, K and L.
- M, N and O.
- P, Q, R and S.
- T, U and V.
- W, X, Y, and Z.
According to the above, the table would be completed as follows.
