Answer:
Length = 29 m
Width = 29 m
Step-by-step explanation:
Let x and y be the length and width of the rectangle, respectively.
The area and perimeter are given by:

Rewriting the area as a function of x:

The value of x for which the derivate of the area function is zero, is the length that maximizes the area:

The value of y is:

Length = 29 m
Width = 29 m
I believe that it is 2,000 because you multiply it by 2 three times.
Answer:
5/8
Step-by-step explanation:
Freddie swam 3/8 laps yesterday
He also swam 1/4 laps today
Therefore the total lap swam can be calculated as follows
= 3/8 + 1/4
= 5/8
Hence the total lap is 5/8
Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees
