Question

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

Answer 1

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.
