pair of adjacent sides of a rectangle are in the ratio 3:4. If its diagonal is 20 cmfind the lengths of the sides and hence, the perimeter of the rectangle.3. |
|
Answer» Given length:breadth = 4:3Let length = 4x and breadth = 3xDiagonal = 20 cmSince the diagonal and the two adjacent sides of a rectangle form a right angled triangleBy Pythagoras theorem, we have20²= (4x)2+ (3x)2400 = 16x2+ 9x2= 25x2⇒ x2 = 16∴ x = 4Hence length = 4x = 16 m and breadth = 3x = 12 mPerimeter of rectangle = 2(length + breadth) = 2(16+12) = 56 m |

2. Adjacent sides of a rectangle are 7 cm and 24 cmagonal. |
|
Answer» In the given figure, ABCD is a rectangle with length 24 cm and breadth 7 cm. Also, in the figure, BCD is a triangle right angled at D. CD = Base = B = 24 cmBD = Perpendicular = P = 7 cmBC = Hypotenuse = H = H So, according to Pythagoras Theorem, Hypotenuse^2 = Base^2 + Perpendicular^2 (H)^2 = (B)^2 + (P)^2 => (H)^2 = (24)^2 + (7)^2 => (H)^2 = 576 + 49 => (H)^2 = 625 => H = √(625) => H = 25 cm Diagonal = Hypotenuse = 25 cm |
