Answers:
1. (1);
Let breadth=x,length=3x
x.3x=7803, x=51
2. (1);
9x.7x=252, x=2
primeter=2(18+14)=64
3.(4);
1=34, 6=204, 5=170
perimeter=2(204+170)=748
4.(5);
8-5=60, 1=20
8=160, 5=100
Perimeter=2(160+100)=520
5. (2);
x.2x=18, x=3
Perimeter=2(3+6)=18
6. (1);
Area=256/2=128
x.2x=128
x=8
Length=2X8=16
7. (3);
Let Length=x and breadth=3/4 x
x.3/4x=300
x=20
Area of garden=(20+3)(15+3) - 300
=144 m^2
8. (4);
9. (2); Length=(361)^1/2=19
Required cost=4X19X62=4712
10.(5); 2 pi. r=88
r=14
Area=pi.r^2
=22/7X14X14=616
