"The length of a rectangle is 5/2 units greater than its width"

'greater' here means multiplication, 5/2 units greater or 5/2 times more. So we know that the length is \sf\dfrac{5}{2}w.

Perimeter of a rectangle is:

\sf P=l+w

Plug in our value for the length:

\sf P=\boxed{\sf \dfrac{5}{2}w+w}

What is the perimeter of a square with side length 13.4 inches
Tamiku [17]
P= perimeter. x= # of inches. 4=number of sides in a square
P= 4x

so, P= 13.4 x 4. Therefore, the perimeter is 53.6 inches.

A triangle has a perimeter of 56 cm. Each of the two longer sides of the triangle is three times as long as the shortest side. W
bagirrra123 [75]

The lenght of each side is 24cm, 24cm, and 8cm.

In order to solve this problem, we know that the perimeter of a triangle equation is P = a + b + c, where a, b, and c are the sides of the triangle.

The perimeter is 56cm, we can write the equation as follow:

a + b + c = 56cm (1)

If each of the two longer sides of the triangles is three times as long as the shortest side, we can assume:

c = shortest side = x

a = b = longer sides = 3x

Substituting the values in the equation (1):

3x + 3x + x = 56cm

7x = 56cm

x = 56cm/7 = 8cm

c = shortest side = 8cm

a = b = longer sides = 3(8cm) = 24cm

What is the missing length?
TEA [102]
Answer:  13.722 km ;  or, write as:  13  13/18 km .
___________________________________________________
Explanation:
___________________________________________________
Area = Length * width ; 
___________________________________________________
or, write as:  A = L * w ;
________________________

Given: A = 247 km² ; 
           
          L = 18 km ; 
 
          w = "y" ; 
________________________
 Find:  "y"
______________________________
  A = L * w ; 
______________________________
Plug in our values:
______________________________
  247 km² = 18 km * "y" ;  solve for "y" (in units of "km") ;

_____________________________
        18 y = 247 ; 
___________________________________________________________
Divide each side of the equation by "18"; to isolate "y" on one side of the equation; and to solve for "y" :
___________________________________________________________
        18 y / 18 = 247 / 18 ;
_____________________________________________
  to get:
_____________________________________________
              y = 13.7222222222222222...... km ;  round to: 13.722 km

                   or;  y = 13  13/18 km .
