What number is 35% of 22?

1 answer:

7 0

<span>The answer is 7.7. Let x be the number we are looking for. So x is 35% and we know that 22 is 100%. Make a proportion: x : 35% = 22 : 100%. Cross the products: x * 100% = 22 * 35%. x * 100% = 770%. x = 770% : 100%. x = 7.7. Thus, 7.7 is 35% of 22. </span>

Length of side of new square is 17 inches

Step-by-step explanation:

Step 1: Let the length of the side of the old square be x. Then length of side of new square = x + 3 and Perimeter of new square = 40 + 2x

Perimeter of a square = 4 × side

⇒ 4(x + 3) = 40 + 2x

⇒ 4x + 12 = 40 + 2x

⇒ 2x = 28

⇒ x = 14 inches

Step 2: Find length of side of the new square

⇒ x + 3 = 17 inches
