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,

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
