Question

If the area of the square of side x is 5. what is the area of the square of side 3x?

Answer 1

Answer:

45

Step-by-step explanation:

that x^2 = 5, so x = √5. Thus, 3x = 3√5, so the area of a side of 3x is (3√5)^2 = 9 x 5 = 45.

Area of square of side x = 5

side × side = 5

$x \times x = 5$

${x}^{2} = 5$

Now, the Area of square of side 3x = Side × Side

$= 3x \times 3x$

$= 9 {x}^{2}$

Replace value of x square here

$= 9 \times 5$

= 45
