Answer 1

Answer:

20 + 8 = 28 .

similarly,

(20 + 8) (20 + 8)

= 28 × 28

= 784 .

Answer 2

Answer:

784

Step-by-step explanation:

(20 + 8)(20 + 8) it's like (a + b) (a +b)

so, let 20 be "a" and 8 be "b"

so now,

(a +b)(a + b)

=a square + b square + 2ab

therefore,

=20 square + 8 square + 2 *20 *8

= 784 is the answer

or else,

20 + 8= 28

so,

28 *28 = 784
