Dth of the rectangle = 12 cm.s and the diagonal is 37e3:= 2x = √144= 12 cmHence, length of the rectangle = 24 cm, and breadth of the restFind the area of a rectangular plot, one side of which measure 26metres.Let the other side bex metres.= (37)2Then (35)2 + x2= 144orx2 = [(37)2-(35)2]= 12Thus, the other side of the rectangle = 12 metres.The area at the rectangle = (35 x 12)m2 = 420 mFind the area of a square, the length of whose diagonal is 3 metres.Area of the square= %*(diagonal)= [22*3*3] m2= 4.5 m2Find the area of the square joining the mid-points of the sides. If the area of square is 16 cm2. |

Answer» Answer:Given :- diagonal = 37 m one of the side ' L ' (length) = 35 m Let width (breadth) = x m {(width)}^{2} + {(length)}^{2} = {(diagonal)}^{2} \\ \\ ({x)}^{2} + {(35)}^{2} = ({37)}^{2} \\ \\ {x }^{2} + 1225 = 1369 \\ \\ {x }^{2} = 1369 - 1225 \\ \\ {x}^{2} = 144 \\ \\ x = \SQRT{144} \\ \\ x = 12 breadth (width) = 'x' m = 12m Area of rectangle = length*breadth = 35*12 = 420m sq.
