Answer:
it is a^2 +b^2 =c^2

Answer:
Answer is 12-19 = -7
Step-by-step explanation:
12- 19 you can break 19 into 12 +7
then
it is easy to find 12-12 = 0
Now subtracts 0 - 7 =- 7
then
break 7 into 3 + 4
then
0 - 3 = -3
-3 - 4 = -7
So ,
12 - 19 = -7
The correct value of the length of a side = 2¼ ft
Answer:
area of the whole mosaic = 182.25 ft²
Step-by-step explanation:
We are told it has a 6 x 6 array of different colour square tiles.
Which means it has 6 x 6 = 36 square tiles.
Area of square = L²
Where L is length of side
Now, since length of one tile is 2¼ ft long.
Thus, area of one square tile = (2¼)²
= 81/16 ft²
Since there are 36 tiles,
Thus ;
Total area ; 81/16 x 36 = 182.25 ft²
