2 . L1 = 14× 7
= 98

L2= 23× 7
= 161

Ltot = 98+ 161
= 259

3.L1 =1/2 ×(8+14)×5
= 1/2 × 24× 5
= 60

L2 = 8×8
= 64

Ltot = 60 +64
=124

4. L1= 1/2 ×(9+6) ×8
=1/ ×15 ×8
= 60

L2= 1/2 (3+6 )× 8
= 1/2 ×9×8
=36

L3 = 6×6
= 36

Ltot = 60+36+36
= 132

5. L1 = 10×10
=100

L2 = 1/2 ×5 ×10
=25

Ltot =100-25
= 75
