For this case we have that by definition, the area of a rectangle is given by:

Where:
w: Is the width of the rectangle
l: is the length of the rectangle
According to the data of the statement we have:

Substituting:

Substituting the values:

Thus, we have two roots:
w_ {1} = \ frac {5+ \ sqrt {157} {2}} = 8.77
w_ {2} = \ frac {5+ \ sqrt {157} {2}} = - 3.77
We choose the positive value. So the width of the rectangle is approximately 8.77 meters and the length is 3.77 meters

Answer:
−63t2−439t−741
Step-by-step explanation:
Let's simplify step-by-step.
9(4+t)−7(t+3)(9)(4+t)−7(t+3)
Distribute:
=(9)(4)+(9)(t)+−63t2+−441t+−756+(−7)(t)+(−7)(3)
=36+9t+−63t2+−441t+−756+−7t+−21
Combine Like Terms:
=36+9t+−63t2+−441t+−756+−7t+−21
=(−63t2)+(9t+−441t+−7t)+(36+−756+−21)
=−63t2+−439t+−741
Answer:
m<B is 48°
Step-by-step explanation:
m<C is already 90°
m<A is 42°
42+90+x=180
132+x=180
x=48°
