students, find out the number of laddoos that remained?
2.
Find the perimeter of the rectangle of length 15cm and breadth 6cm.
3. Find the LCM of 14 and 28
4. Find the H.HC.F of 28 and 56
5. If 2 angles of triangle are 65 degree and 75 degree find the measure of 3 angle
6. Draw a circle of 3cm radius and show the radius diameter​

Answer 1

Step-by-step explanation:

1) total laddoos=200

distributed=90%

remaining=(100-90)%=10%

10%of 200= (10/100)*200= 20

remaining laddoos are 20

2) perimeter=2*(l+b)

= 2*(15+6)=2*21=42cm

3) lcm of 14,28 is 28

4) hcf is 2*7 = 14

5) 1st angle+2nd+3rd angle=180°

= 65°+75°+3rd angle=180°

=3rd angle=180°-65°-75°

=180°-140°=40°
