<span>The area of a triangle is 6.75 m^2
=> (1/2) x base x height=</span>6.75 m^2
=>(1/2) x 3 x <span>height = </span>6.75
=><span>height = (</span>6.75x2)/3= 4.1
so the height is 4.1m
P(green)=2/10=1/5
P(red, no replacement)=6/9=2/3
So, 1/5(2/3)=2/15

Step-by-step explanation:
Cameron task: 3/7 × 2/9
What he did:
• Simplify 3/7 to 1/7
• mulitiplied the fractions 1/7 and 2/9
Cameron's error was:
• The "simplification":
To simplify a fraction is to reduce to the lowest possible multiple. Illustration:
Simplify 16/100
= 2/25
But in the case of 3/7, the answer is 3/7.
What Cameron would have done:
1. 3/7 = 2/7 + 1/7
3/7 × 2/9 = (2/7 × 2/9) + (1/7 × 2/9)
= 4/63 + 2/63
= 6/63
2. since he simplified 3/7 to 1/7
1/7 = 3/7 × 1/3
Therefore,
3/7 × 2/9 = 1/7 × (2/9 × 3)
= 1/7 × 6/9
= 6/63
