Answer:
perimeter of figure is = 38cm
area of figure is = 80cm^2
Answer:
38 cm
Step-by-step explanation:
Here, you can see opposite sides of the rectangle has different measure ( 7 ≠ 11 and 8 ≠ 6)
so, we can say that the diagram is not perfect rectangle
but we know that adding all sides of a shape gets a perimeter so we have some measures - 7 ,11 ,8 ,6 ,a ,b ) where 'a' and 'b' are unknown numbers.
Hence, first we need to find the value of a and b and then add all numbers...
Let's take
=> 8 = a + 6 (here both lenght of the both sides of
rectangle are same)
a = 8 - 6 ( Transposing the term)
Therefore, a = 2
=> 11 = b + 7
b = 11 - 7 ( Transposing the terms )
Therefore, b = 4
Next we need to add them
=> a + b + 11 + 7 + 6 + 8
=> 2 + 4 + 11 + 7 + 6 + 8 = 38 cm ( changing the
variables to
constant)
here, this might help you...
