Let ABCD and EFCD be two parallelograms lying on the same base CD and between the same parallels AF and CD.
We have to prove that area of the parallelograms ABCD and EFCD are equal.
In ADE and BCF,
DAE = CBF (Corresponding angles)
AED = BFC (Corresponding angles)
AD = BC (Opposite sides of the parallelogram ABCD)
ADE BCF (By ASA congruence rule)
We know that congruent figures have the same area.
area (ADE) = area (BCF) … (1)
Now, we have:
area (ABCD) = area(ADE) + area (EDCB)
= area (BCF) + area (EDCB) [Using (1)]
= area (EDCF)
Thus, the areas of the two parallelograms ABCD and EFCD are the same.

Perimeter = 32 cm, a = 8 cm, b = 11 cm
Perimeter = a + b + c
32 = 8 + 11 + c
32 = 19 + c
c = 32 - 19 = 13
S= 32/2 = 16 cm
Area of triangle = √s(s- a) ( s - b) (s-c)
= √ 16 (16 - 8) (16 -11) (16-13)
= √16 (8) (5) (3) cm2
Area of triangle = 8√30 cm2

A n s w e r :
3 (2a-b-c) (2b-c-a) (2c-a-b)
Step - by - step explanation :
We know that, if x+y+z=0; then x 3+y 3+z 3=3 x y z
(2a-b-c)+(2b-c-a)+(2c-a-b)=0
∴ (2a-b-c)3+(2b-c-a)3+(2c-a-b)3= 3(2a-b-c)(2b-c-a)(2c-a-b)

According to the given statement,
y = x/2 - 10
or 2y = x - 20
or x - 2y = 20
Thus the above linear equation represent the given statement.

Let the two given numbers be a and b respectively a= 1 and b=2
We know that the rational number between a and b is given by (a + b)/2
So the rational number between 1 and 2 = (1+2)/2 = 3/2
Then, Rational number between 1 and 3/2 =[1+(3/2)]/2 = 5/4
Then Rational number between 1 and 5/4 =[1+(5/4)]/2 = 9/8
Then Rational number between 3/2 and 2 =[(3/2) + 2]/2 = 7/4
Then Rational number between 7/4 and 2 =[(7/4) + 2]/2 = 15/8 Hence the five rational numbers between 1 and 2 are 3/2, 5/4, 7/4, 9/8, and 15/8
