Question

the perimeter of a square are in the ratio of 18 : 15 find the ratio between the length of their sides​

Answer 1

Answer:

Step-by-step explanation:

Let the side be s ,

So,4s is equal to 18x of first square ,

And,4s is equal to 15x in second square ,

Ratio = 18x:15x ,

⇒ 18:15.

Answer 2

Ratio of side = 6:5

GIVEN:

perimeter of a square are in the ratio = 18 : 15

TO FIND:

Ratio of the side of two square

SOLUTION:

$\frac{perimeter \: of \: 1st \: square}{perimeter \: of \: 2nd \: square} = \frac{18}{15} \\ \frac{4 \times side \: of \: 1st \: square}{4 \times side \: of \: 2nd \: square} = \: \frac{6}{5} \: (divide \: by \: 3) \\ \frac{side \: of \: 1st \: square}{ side \: of \: 2nd \: square} = \: \frac{6}{5}$

Ratio of side of two square = 6:5

SOME IMPORTANT FORMULAS:

Perimeter of a square = 4 * side

Area of square = (side)^2
