Given : ABCF is a Rectangle
⇒ AB = CF
Given : AB = 6 cm
⇒ CF = 6 cm
Perimeter of a Rectangle is given by : 2(Length + Width)
Given : Perimeter of the Rectangle = 20 cm
⇒ 2(6 + BC) = 20
⇒ 6 + BC = 10
⇒ BC = 4
Given : BD = 9
But, We can See that : BD = BC + CD
⇒ CD + 4 = 9
⇒ CD = 5
We know that :
✿ 
Where : a and b are Lengths of Parallel Sides and Height is Length between those Parallel Sides
In the Given Trapezium :
The Parallel Sides are CD and EF and Height is CF
Given : EF = 3 cm


Answer:
10%
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
replace a with 2 and b with 3 in the expression and solve as follows
(2 + 5)-3 / 3-4 + 2(3+3)/ 2
7 - 3/-1 +12/2
14 + 6 +12/2
32 / 2
