Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.
Little square

Answer:
The class will pay $82.50
Step-by-step explanation:
The zoo is covering 60%.
The school is covering 25%.
60% + 25% = 85%
100% - 85% = 15%
That leaves 15% to be paid by the science class.
To figure out what 15% of $550, we can multiply $550 by 0.15.
$550 * 0.15 = $82.50
So, the class will pay $82.50

Answer:
Cost Price
12
40
=3.33 rupees/banana
Selling Price
10
36
=3.6 rupees/banana
Therefore,
It is 43.2 for 12 bananas
Profit=SellingPrice−CostPrice
=43.2−40=3.2
Therefore,
Profit %=
40
3.2
×100
=8% profit
Hence, this is the answer.
