Answer 1

#A:

(a)There are 27 non square numbers between 13² and 14².

(b)First 4 triangular nos. are 1, 3, 6, 10,

(c) A "Pythagorean Triple" is a set of positive integers, a, b and c that fits the            rule:

a2 + b2 = c2

then 5;7;9

5 square+ 7 square = 9 square

25+49 = 81

74 = 81

then 5;7;9 not Pythagorean triplet.

(d) The square root of 9 is 3.

Now

Step 1:9 - 1 = 8

Step 2:8 - 3 = 5

Step 3: 5 - 5 = 0

(e)Side of the square = 18 cm

Step-by-step explanation:

Let side of a square = a cm,

Area of the square (A)

=324 cm²

=> a² = 324 cm²

=> a² = (18 cm)²

=> a = 18 cm

Therefore,

side of the square = 18 cm
