$\huge{\underline{\underline{\mathfrak{\purple{explanation}}}}}$

Here value of

• PQ = 6.8 cm
• ST = 3.4 cm

SO PUTTING VALUE IN

1 QUESTION )

• PQ + ST
• ( 6.8 + 3.4 )cm
• 10.2 cm

2 Question )

• PQ - ST
• ( 6.8 - 3.4 )cm
• 3.4 cm

3 QUESTION )

• PQ - 1/2 ST
• [ 6.8 - ( 1/2 × 34/10 )]cm
• [ 6.8 - 1.7 ]cm
