Across-shaped pattern is made by arranging four identical rectangles around the side of a square, as shown in the diagram. the area of the square is 36cm^2. the area of each rectangle is one and a third times the area of the square. find the perimeter of the cross-shaped pattern. show your working and state the units of your answer. awarding 15 points. someone answer correctly quick, much appreciated x

88 cm

Step-by-step explanation:

The composite figure is made by arranging four identical rectangles around the side of a square.

The area of the square is .

So the side length of the square is,

The area of each rectangle is of the area of the square.

So the area of each rectangle is,

As the breadth of each rectangle is equal to the side length of the square i.e 6 cm, so

Then perimeter of the cross pattern figure will be,

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
