Three would be your answer :)
Is to long to explain so I'm doing quite
find the triangle side so 2.1 square minus 1.4 square it is equal to 2.45
now you just multiple 2.45 by 2 because if you notice 2.45 is the triangle side that is missing and this is only the half so multiple by 2 for get the X value, I hope this helps you.

Answer:

Step-by-step explanation:
We know that the shop only buys Banana with lengths between 13 cm and 20 cm.
So, the fraction of the 80 bananas is actually a ratio between the y-values of each length (13 and 20 cm) and the total 80. First, let's see which y-values belong to each length.
Notice that 13 below to 20 at Cumulative Frequency. And 20 belongs to 62. So, the pairs are (13,20) and (20,62).

Therefore the shop only buys 42 bananas out of 80, because those are between 13 cm and 20 cm.
You have a trapezoid and a triangle...
area of a trapezoid=height*(base1+base2)/2
a1=3(12+8)/2=30 ft^2
area of triangle=hb/2
a2=4(12-8)/2=8 ft^2
a1+a2=38 ft^2
