Answer 2

15.5 cm × 8.2 cm = 127.1 cm²

Given:

15.5 cm × 8.2 cm

To Find:

Evaluate

Solution:

Multiply

15.5 cm × 8.2 cm

= (15.5 x 8.2) cm²

= (155/10) x( 82/10)

= (155 x 82) /100

Calculate 155 x 82

= (150 + 5) x ( 80 + 2)

= 150 x 80  + 150 x 2  + 5 * 80  + 5 * 2

= 12000 + 300 + 400 + 10

= 12710

Evaluate

(12710)/100

= 1271/10

= 127.1

Hence 15.5 cm × 8.2 cm = 127.1 cm²
