Alright, so let's make the length x and the width y. 2y=x, and xy=area. 2x+2y=perimeter. Plugging 2y=x into the perimeter equation, we get that 3x=perimeter=126, and x=126/3=42
Length=42ft, width=21ft
Answer:
12
Step-by-step explanation:
16 divided by 4 is 4
8 + 4 : 12
We have
1G = 12.05 - 3D;
Then,
2D + 3( 12.05 - 3D) = 15.50;
2D + 36.15 - 9D = 15.50;
- 7D = - 20.65;
D = 2.95;
Finally, G = 12.05 - 3 x 2.95;
G = 3.20;
