A rectangle has a length 10 m less than twice its width. When 2 m are added to the​ width, the resulting figure is a square with
dolphi86 [110]

Answer:

The length of the original rectangle is 14 meters and the width of the original rectangle is 12 meters

Step-by-step explanation:

Let

l ----> the length of the original rectangle

w ----> the width of the original rectangle

we know that

l=2w-10 ----> equation A

196=(w+2)^{2} ----> area of a square

Solve for w

square root both sides

(w+2)=(+/-)14

w=14=(+/-)14-2

w=14=14-2=12\ m

w=14=-14-2=16\ m -----> this solution not make sense

so

w=12\ m

Find the value of L

l=2(12)-10=14\ m

therefore

The length of the original rectangle is 14 meters and the width is 12 meters

Solve for unknown values.
forsale [732]
Firstly, a straight line = 180 degrees.
Based on the statement above, we can create an equation of 180-95 = x
(Which is 85)
Now, we also know that all of the angles in a triangle add up to 180 degrees, so we can create this equation of 180- (85 + 50) = y
(Which is 45)
