Answer: perimeter = 96mm, Area = 564mm².
Step-by-step explanation:
From the diagram, it is a trapezium, it has a rectangle joined together by a right angled triangle. Now to find the perimeter, we add all the dimensions together. To get the other side of the rectangle, which is also the perpendicular height of the figure, we take the Pythagoras. Let the perpendicular height = x
Therefore,
25² = ײ + 7²
625 = x² + 49
x² = 625 - 49
x² = 576
x. = √576
= 24.
Now the perimeter
= 20 + 25 + 7 + 20 + 24
= 96mm.
Area of the figure will be
= 1/2( a + b )h
Where a = 20, b = 20 + 7 = 27 and h = 24, now substitute for the values
( 20 + 27) x 24
---------------------
2
= 47 x 24/2
= 47 x 12
= 564mm²
Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
In case of Alpha:
Number of oranges = 18
Number of apples = 9
In case of Beta :
Number of oranges = 16
Number of apples = 4
We need to find the opportunity cost of producing 1 orange for Alpha and Beta.
Opportunity cost for Alpha is given by
Opportunity cost for Beta is given by
Hence, Opportunity cost for producing 1 orange for Alpha and Beta are 9 apples and 4 apples respectively.
Hence, Option 'B' is correct.
