Write down your answer and show how you worked out your answer.​

a = 9 cm  

Step-by-step explanation:

We are given that

perimeter of shaded area = 1 m = 100 cm

But according to given diagram

The perimeter of shaded area = ( 3a + 2a + 2 + 2a + 3 + 2 + 3a + 3 ) cm

                                                 = (10a + 10) cm

By using given perimeter = 1 cm we get

The perimeter of shaded area = ( 10a + 10 ) cm = 100 cm

                                           10a = 90 cm

                                               a = 90 / 10 = 9 cm

Thus

                                                a = 9 cm                    

Hope this helps!

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
