I know that 20 times 7 is 140 and if I take away 2 sevens that leaves 126. So 126 \div 7 = 18
Answer:
Step-by-step explanation:
Width = x
Length = 2x
Area of the ground = 0.125 square mile
length * width = 0.125
2x * x = 0.125
2x² = 0.125
x² = ![\frac{0.125}{2}\\\\](https://tex.z-dn.net/?f=%5Cfrac%7B0.125%7D%7B2%7D%5C%5C%5C%5C)
= 0.0625
![x^{2}=\frac{625}{10000}\\\\x=\sqrt{\frac{625}{10000}}\\\\ x=\frac{25}{100}\\\\x=0.25](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D%5Cfrac%7B625%7D%7B10000%7D%5C%5C%5C%5Cx%3D%5Csqrt%7B%5Cfrac%7B625%7D%7B10000%7D%7D%5C%5C%5C%5C%20x%3D%5Cfrac%7B25%7D%7B100%7D%5C%5C%5C%5Cx%3D0.25)
Width = 0.25 miles
Length = 2* 0.25 = 0.50 miles

Answer:
The area of the triangular sail is 216 ft²
Step-by-step explanation:
Since the sail is triangular, we solve the area using the area of a triangle
Area of triangle = 1/2 of base × height
base is 18 and height is 24
Area = 1/2 × 18 × 24
= 9×24
= 216 ft²
