Answer:
26 square units
Step-by-step explanation:
Counting grid squares on the graph, we see that segment AB is the hypotenuse of a right triangle with legs 2 and 3. Its length is ...
AB = √(2²+3²) = √13
We can also see that the adjacent longer sides are twice this length, each being the hypotenuse of a triangle that is 6 wide and 4 high.
AC = √(6² +4²) = √52 = 2√13
Then the area is ...
A = LW
A = (2√13)(√13) = 2·13 = 26 . . . square units
A)
Earlier, The length of the angelfish = inches
Now, the length of angelfish = inches
We have to determine the grown length of angelfish
= -
=
LCM of '2' and '3' is '6',
=
= inch
Therefore, the angelfish has grown by inch.
B)
We have to determine the increased length of angelfish in feet.
Since foot
So,
= 0.069 foot.
