Answer 2

If 5*7 = 109 , 3*6 = 63 , 11*8 = 273 then the value of 16*8 = 448

Given :

5*7 = 109 , 3*6 = 63 , 11*8 = 273

To find :

The value of 16*8

Solution :

Step 1 of 3 :

Write down the given data

Here it is given that

5*7 = 109 , 3*6 = 63 , 11*8 = 273

Step 2 of 3 :

Find the pattern

5*7 = 5² + 7² + ( 5 × 7 ) = 25 + 49 + 35 = 109

3*6 = 3² + 6² + ( 3 × 6 ) = 9 + 36 + 18 = 63

11*8 = 11² + 8² + ( 11 × 8 ) = 121 + 64 + 88 = 273

Thus the pattern is

a*b = a² + b² + ( a × b )

Step 3 of 3 :

Find the value of 16*8

16*8

= 16² + 8² + ( 16 × 8 )

= 256 + 64 + 128

= 448
