The area of a rectangle is 33 m2 ,
Vika [28.1K]

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

A = w * l

Where:

w: Is the width of the rectangle

l: is the length of the rectangle

According to the data of the statement we have:

A = 33 \ m ^ 2\\l = w-5

Substituting:

w (w-5) = 33\\w ^ 2-5w-33 = 0\\\\So:\\w = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}\\a = 1\\b = -5\\c = -33

Substituting the values:

w = \frac {- (- 5) \pm \sqrt {(- 5) ^ 2-4 (1) (- 33)}} {2 (1)}\\\\w = \frac {5 \pm \sqrt {25 + 132}} {2}}\\\\w = \frac {5 \pm \sqrt {157}} {2}}

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:

l = 3.77 \ m\\w = 8.77 \ m

A squirrel climbs up a tree. She starts at 0.5 feet up the tree, then climbs at a steady pace for 7.5 seconds. She ends 4 feet u
Xelga [282]

Given :

A squirrel climbs up a tree. She starts at 0.5 feet up the tree, then climbs at a steady pace for 7.5 seconds.

She ends 4 feet up the tree.

Solution :

Now, distance covered is :

d = 4 - 0.5 = 3.5 feet.

Time taken, t = 7.5 seconds.

Distance climbed per second is :

D =\dfrac{d}{t}\\\\D=\dfrac{3.5}{7.5}\\\\D = 0.467\ feet/s

Therefore, distance climber per second is 0.467 feet.

Hence, this is the required solution.
