If the sides of a rectangular plot are 40 m and 9 m, then the length of its diagonal is :

• 31 m

• 41 m

• 45 m

• 49 m

 $In\ a\ right\ angled\ \Delta$ , if the lengths of the sides containing the right angle are 20 cm and 21 cm, then the length of its hypotenuse is :

• 24 cm

• 25 cm

• 26 cm

• 29 cm

If a man goes 15 m due north and then 8 m due east, then his distance from the starting point is :

• 7 m

• 17 m

• 23 m

• 120 m

AD is drawn  $\perp$  to base BC of an equilateral  $\Delta$   ABC. If BC = 10 cm, then the length of AD, correct to one place of decimal is 

•  $8\cdot5\ cm$  

•  $8\cdot6\ cm$  

•  $8\cdot7\ cm$  

•  $8\cdot8\ cm$  

 $In\ a\ right\ angled\ \Delta$ , if hypotenuse is 10 cm and the ratio of the other two sides is 3 : 4, then these sides are : 

• 6 cm and 8 cm

• 9 cm and 12 cm

• 3 cm and 4 cm

• 9 cm and 16 cm
