Answer:

The length of the rectangle is 18 cm

The width of the rectangle is 6 cm

Step-by-step explanation:

Let

x-----> the length of the rectangle

y----> the width of the rectangle

we know that

The perimeter of the rectangle is

P=2(x+y)

we have

P=48\ cm

so

48=2(x+y) ------> equation A

x=2y+6 ------> equation B

Substitute equation B in equation A and solve for y

48=2(2y+6+y)

48=2(3y+6)

48=6y+12

6y=48-12

y=36/6=6 cm

Find the value of x

x=2(6)+6=18 cm

The area of the rectangle is

A=xy

A=18*6

A=108 cm^2

White raven [17]
You could do x=81 with the little line on the top (represents the number going on forever, and example is 0.818181818181818181818181818818181818 etc.)

Find the value of x.<br><br> Please help and can somebody tell me how to find x?
Olegator [25]

Answer:

x = 75°

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

Therefore,

78° + 27° + x° = 180°

Add like terms

105 + x = 180

105 + x - 105 = 180 - 105 (substraction property of equality)

x = 75°
