What is the area of this irregular figure?

A figure can be broken into a rectangle and triangle. The rectangle has a base of 6 centimeters and height of 6 centimeters. The triangle has a base of 6 centimeters and height of 6 centimeters.
54 Centimeters squared
72 Centimeters squared
216 Centimeters squared
432 Centimeters squared

Area of rectangle = 6 x 6 = 36 centimeters squared

Area of triangle = 1/2 x 6 x 6 = 18 centimeters squared

Total area = 36 + 18 = 54 centimeters squared.

54 cm^2

Step-by-step explanation:

First find the area of the rectangle

A = l*w

A = 6*6

A = 36 cm^2

Then find the area of the triangle

A = 1/2 bh

  = 1/2 (6)*6

   = 18

The total is

A =36+18 =54

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
