Answer:
10. 3x-1 x=1
=3(1)-1
=3-1 answer =2
11. Circle radius =14cm
Area =pi r2
22/7 * 14*14
616 cm2
12. Area of square = s*s
Area =5.8 *5.8
Area =33.64
13. Diameter =21 cm
R=d/2
21/2 = radius =10.5
Circumference=2 pi r
2/1* 22/7 * 10.5
=462 /7 = 66cm
14. IDK
15. x/4 =7
x = 7 *4
x= 28
16. Take 90' C and draw it out...
17. 5x =x-8
5x-x= - 8
4x = - 8
x = - 8 - 4
x = - 12
18. Radius =52 cm
Diameter = r *2
= 52 * 2
=104
19. Area = pi r 2
Radius = 7 cm
22/7 7 *7
=154 cm2
20. Area of parallelogram = base * length
= 6 cm * 4cm
24 cm 2

I hope this will be helpful for you..
