Construct a rectangle WXYZ where WX = 5 cm and WY = 7cm.8. The sides of a rectangle are in the ratio 2:3, and perimeter is 20 cm. Draw the rectangle. |
| Answer» CT a rectangle ABCD given1. AB = 6 cm, BC = 5 cmWe know that in rectangle measure of each angle is 90° and opposite sides are equal.⇒ Draw a line segment AB=6cm.⇒ CONSTRUCT angle of 90o at POINTS A and B⇒ CUT off AD=5cm and BC=5cm⇒ Join CD.Construct a rectangle ABCD givenAB = 5.8 cm, BC = 4.6 cm ⇒draw a line segment AB = 5.8 cmdraw an angle of 90° from both A and B (since , angle in the rectangle is 90°)⇒open compass 4.6 cm and from B mark the point C on line BL ∴ BC = 4.6 cm⇒same with A mark a point D on the line AM .∴ join C to D .⇒then, ABCD is the required rectangle.Construct a triangle ABCD given AB = 7 cm, BC =5.5 cmWe know that in rectangle measure of each angle is 90o and opposite sides are equal.⇒ Draw a line segment AB=7cm.⇒ Construct angle of 90o at points A and B⇒ Cut off AD=5.5cm and BC=5.5cm⇒ Join CD. | |
