I'm not sure what this question means exactly, maybe the principals goal is unrealistic?
The area <em>A</em> of a trapezoid with height <em>h</em> and bases <em>b</em>₁ and <em>b</em>₂ is equal to the average of the bases times the height:
<em>A</em> = (<em>b</em>₁ + <em>b</em>₂) <em>h</em> / 2
We're given <em>A</em> = 864, <em>h</em> = 24, and one of the bases has length 30, so
864 = (<em>b</em>₁ + 30) 24 / 2
864 = (<em>b</em>₁ + 30) 12
864 = (<em>b</em>₁ + 30) 12
72 = <em>b</em>₁ + 30
<em>b</em>₁ = 42
Answer: 40% and 0.4
Step-by-step explanation:
Note that 1 meter = 100 centimeters, so 1.3 meters = 130 centimeters
It grew another 22 cm
130 + 22 = 152
152 cm is your answer
