The area of a square is 144cm2.what is the measurement of each side​
Dmitry [639]

The area of a square is 144 cm^2. The measurement of each side​ is 12 cm

<u>Solution:</u>

Given, The area of a square is 144 cm^2

We have to find that what is the measurement of each side.

Now, we know that, area of a square = product of side value with another side value.

Let the side value of given square be "s"

Then, <em>Area of square is given as:</em>

\begin{array}{l}{\text {area of square}=s \times s} \\\\ {\text {Area of square}=s^{2}} \\\\ {144=s^{2}} \\\\ {s=\sqrt{144}} \\\\ {s=\sqrt{12^{2}}}\end{array}

On cancelling square root and square on right side,we get

s = 12

Hence, the side value of the square is 12 cm.

Suppose a varies directly as b, and a=7 when b=2 find b when a =21
kozerog [31]
Because α varies directley to β
\alpha = k \beta
(k = constant)

α=7 when β=2
7= 2k
k= \frac{7}{2}

so when α=21
21= \frac{7}{2} b
b= 6

Decrease 18•4 in the ratio 3:8
andrezito [222]

Answer:

6.9

Step-by-step explanation:

Since you are supposed to decrease the number in the ratio 3:8 or 3/8 you take the small number that is 3 to be the numerator and 8 to be the denominator then multiply it by 18.4.

That is 18.4×3:8= 184/10×3/8=6.9

So to decrease a number you multiply it with the smallest number as the numerator and the big number as the denominator

To increase a number you multiply it with the big number as the numerator and the small number to be the denominator
