W= width
l= 2w= length
Area= length * width
substitute l= 2w for the length
72= 2w * w
72= 2w^2
divide both sides by 2
36= w^2
take the square root of both sides
6 inches= w
Substitute to find length:
2w= 2(6)= 12 inches
CHECK:
72= 6 * 12
72= 72
ANSWER:
Width= 6 inches; Length= 12 inches

Answer:
Step-by-step explanation:
We could use the Law of Sines if we only knew what angle A was. It just so happens that by the Triangle Angle-Sum Theorem, angle A is equal to
180 - B - C. Therefore,
angle A = 180 - 11 - 75 so
angle A = 94. And the Law of Sines is
and cross multiply to get
600sin94 = asin11 and solve for a:
gives you that
a = 3136.85
Answer:
1.82
Step-by-step explanation:
1 × 1 + 8 × 0.1 + 2 × 0.01
1 + 0.8 + 0.02
1.8 + 0.02
1.82
