Answer:

  • 163 in²

Step-by-step explanation:

To find the area, I divided the shape into squares and rectangles. Then, I found the area of the squares and rectangles and added them,

  • Area = (7 x 7) + (18 x 5) + (6 x 4)
  • => (49) + (90) + (24)
  • => 163 in²

Hence, the area is 163 in.²

Can you answer these 3 questions for me plz

A.
1hr \: 15min = 75min

c = 0.22t = 0.22 \times 75 = 16.5

cost is $16.50

B.

26.40 = 0.22 \times t

rearrange to solve for t:

t = \frac{26.40}{0.22} = 120min

C. This is the same as part B, only the rate changed

t = \frac{26.40}{0.25} = 105.6min

they ask for the greatest number of minutes, so we round down (take the floor of the value).

the answer is 105 minutes.

<em>Then evaluate</em>

1+5.76=c^2

<em>Add</em>

c^2=6.76
