To find the perimeter of the rectangle you can use the expression 2 L t 2 w where L and w represent the length and width of the rectangle. Find the perimeter of a rectangle with length 4m and width 7m.

22 m.

Step-by-step explanation:

Perimeter = 2*4 + 2*7

= 8 + 14

= 22 m.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
