If A(-2, -1), B(a,0), C(4,b) and D(1,2) are the vertices of a parallelogram. Complete activity to find the values of a and b. Activity : A(-2,-1), B(a,0), C(4,0) and D(1,2) are the vertices of a parallelogram Diagonals of parallelogram bisect each other :. midpoint of diagonal AC = Midpoint of diagonal BD By midpoint formula, ((-2 + 4)/(2), (-1 + b)/(2)) = ((a + 1)/(2), (square)/(square)) :. (square, (-1 + b)/(2)) = ((a + 1)/(2), 1) {:( :. square = (a + 1)/(2)),("on simplifying, we get"),(a = square):}|:{:((-1 + b)/(2) = square),("on simplifying, we get"),(b = square):}

The area of the region enclosed by the curves y=x,x=e,y=(1)/(x) and the positive x-axis is (1)(1)/(2) square units (2)1 square units (3)(3)/(2) square units (4)(5)/(2) square units

Complete the following activity to solve simultaneous equations : 4x+ 3y = 18 " "...(1) 5x - 3y = 9 " " ...(2) Adding equations (1) and (2) , +{:(4x+3y=18" ...(1)"),(5x-3y=9" ...(2)"),(bar(squarex" "=square)):} :. X = (square)/(square ) " " :. X = square Substituting x = 3 in equation (1) , 4 xx square + 3y = 18 " " :. 3y = 18 - square " " :. 3y = square :. y = 2 (x,y ) = (square, square ) is the solution
