Find the area the figure is not drawn to scale 6.9 cm 4 cm
1 answer:
Please check attached file to see if you mean the same triangle.
Basically, to find the area of a triangle, you are going to use the formula :
A = b × h where b is base, h is height.
2
others also use the formula: <span> Area=1/2(bxh)</span>
Based on the figure, we have 6.9 cm (base) and 4 cm (height) as given.
Let us work out on the area of the said triangle.
A= <u>6.9cm × 4cm</u>
2
= <u>27.6cm</u>²<u>
</u> 2
A= 13.8 cm²
Hope this helps!

Answer:
James bought 11 good tickets and 5 bad tickets.
Step-by-step explanation:
Given that:
Cost of each good ticket = $8
Cost of each bad ticket = $5
Total amount spent = $113
Total tickets bought = 16
Let,
x be the number of good tickets bought
y be the number of bad tickets bought
x+y=16 Eqn 1
8x+5y=113 Eqn 2
Multiplying Eqn 1 by 5
5(x+y=16)
5x+5y=80 Eqn 3
Subtracting Eqn 3 from Eqn 2
(8x+5y)-(5x+5y)=113-80
8x+5y-5x-5y=33
3x=33
Dividing both sides by 3
Putting x=11 in Eqn 1
11+y=16
y=16-11
y=5
Hence,
James bought 11 good tickets and 5 bad tickets.
