Answers

There are four rectangles and 2 squares.

Let’s start with the four rectangles.
4 [ 2x(x)]
4 [ (2*7)(7)] = 392 cm^2
______________

Next, let’s find the SA for the two squares.
2 [(2x)^2]
** I need to be clear that both the 2 and the x in the parentheses are squared because the square, of course, is a “perfect square”. This was probably obvious and needless to say, haha oh well.
Next step: plug in values
2 [ [2(7)]^2 ] = 392 cm^2

TOTAL: 392+392 = 784 cm^2

Wow I should have realized the the 4 rectangles are the area as the two squares.

Good luck to you!

Father has 240 oranges in a bag . His neighbor gets 25% of it , his niece gets 1/3 of the reminder and the rest were sold in bags of 5 for 15 . How much money did he earn from the oranges he sold ?​

Answers

Answer:

he made $360

Step-by-step explanation:

25% of 240

240 × 25 ÷ 100 = 60

his neighbor got 60 orange

remainder is 3/4 or 75 %

75% of 240

240 × 75 ÷ 100 = 180

1/3 of 180

1/3 × 180 = 60

he niece got 60 orange

remainder of orange is 2/3

2/3 = 2/3 × 180 = 120

120 ÷ 5 = 24

he sold 24 bags of orange

24 × 15 = $360

he made $360 from his orange
