    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)

    Find six rational no. Between 3 and 4? Answer: to find 6 rational no. Between 3 and 4 denominator should be made equal to 6+1=7. Therefore, 3 = 3*7/7 = 21/7 4 = 4*7/7 = 28/7 Six rational nos. Between 3 and 4 can be found by varying the numerators between 21 and 28. Or the nos. are 22/7 , 23/7 , 24/7 , 25/7 , 26/7 , 27/7.

    Yogita Ingle 5 years, 4 months ago

    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

    We can write 1 and 2 as rational numbers with denominator 6 1=6/6,2=12/6 Then 7/6,8/6,9/6,10/6,and11/6are the numbers between 1 and 2. So, five rational numbers are 7/6,4/3,3/2,5/3 and 11/6.
