Answer:
1. width is w. length is w + 26
2.

3. the width must be less than 34
4. sure, if the width is 10, then the area is 360
Step-by-step explanation:

1
It will be
3 4/14+2 3/14+4 6/14=9 13/14
Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40
Answer: The length and width are 50 and 30 meters (or 30 and 50 meters).
Step-by-step explanation:
To solve this question, we can represent variables for the length and width in two equations.

To solve for one of the variables, you'll have to substitute one of the variables, so solve for one of them:


Now, we have a standard quadratic equation that we can factor. When factoring, you'll get this:

This tells us that the width could be either 50 or 30.
Substitute 50 into one of the equations to find the length:
2 (l) + 100 = 160
l = 30.
The length and width are 50 and 30 meters (or 30 and 50 meters).
Answer:
310.86ft²
Step-by-step explanation:
30/2 = 15
3.14*15² = 706.5
30+3+3 = 36
36/2 = 18
3.14*18² = 1017.36
1017.36 - 706.5 = 310.86
