Length of poster = 20cm

Breath of poster = 16 cm

3.5 cm margin on each side means

Therefore,

Length of Poster= 20 + 3.5 + 3.5 = 27cm

Breath of Poster= 16 + 3.5 + 3.5 = 23cm

⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐
==================================

Area of poster = (20×16) cm² = 320 cm²

Now, length of cardboard

= (20+3.5+3.5) cm

= 27 cm

Breadth of cardboard

= (16+3.5+3.5) cm

= 23 cm

Area of cardboard sheet

= (23×27) cm²

= 621 cm²


Total Area of margin

= (621-320) cm²

= 301 cm² [ANSWER (a)]


Now, in 1 cm², cost is ₹ 1.50

So, in 621 cm², cost is ₹ (1.50×621)

= ₹ 931.50 [ANSWER (b)]
