Answer 1

Answer:

the answer will be 16 cm.

Step-by-step explanation:

Let,

the lenght of MN=x cm.

lenght of LM=12 cm

lenght of LN=20 cm.

we know that,

height sq. + base sq. =hypotenuse sq.

=12 sq. + x sq. =20 sq.

=x sq. =20 sq. - 12 sq.

= x sq. = (20+12)(20-12) [a sq. - b sq. =(a+b)(a-b)]

=x sq. = 32 × 8

=x sq. = 256

=x sq. =2×2×2×2×2×2×2×2

=x sq. = 2 sq×2 sq×2 sq×2 sq

= x =√(2×2×2×2) sq.

= x =2×2×2×2

= x =16

the length of MN=x cm=16 cm.
