S_1 = \frac{a+b}{2}h = \frac{7+9}{2}*5=\frac{18*5}{2}= 9 * 5 = 45~m^2

S_\triangle = \frac{ab}{2} = \frac{5*9}{2} = \frac{45}{2} = 22,5~m^2

S = S_1 + S_\triangle = 45 + 22,5 = 67,5~m^2

Answer: 67,5 m².

The answer is 48 can someone explain how?
mestny [16]

Answer:

<h2>48</h2>

Step-by-step explanation:

(1)

apple × apple × 2apple = 54

2apple³ = 54    <em>divide both sides by 2</em>

apple³ = 27 → apple = ∛27

apple = 3

(2)

apple + apple × green_apple = 24   <em>substituite apple = 3</em>

3 + 3 × green_apple = 24        <em>subtract 3 from both sides</em>

3 × green_apple = 21         <em>divide both sides by 3</em>

green_apple = 7

(3)

strawberry - bannana - banana = 0 → strawberry = 2banana

(4)

strawberry + banana + cherry = 24     <em>substitute from (3)</em>

2banana + banana + cherry = 24

3banana + cherry = 24

(5)

apple + banana - cherry = -1          <em>substitute apple = 3</em>

3 + banana - cherry = -1         <em>subtr3 from both sides</em>

banana - cherry = -4

Add both sides of (4) and (5)

 3banana + cherry = 24

<u>+banana - cherry = -4       </u>

4banana = 20       <em>divide both sides by 4</em>

banana = 5

Substitute it to (4):

3(5) + cherry = 24

15 + cherry = 24      <em>subtract 15 from both sides</em>

cherry = 9

Substitute to the last equation:

3 + 5 × 9 = 3 + 45 = 48
