There are 2 squares, and the ratio of their perimeters is 5: 8. if the area of the first square is 225m², then what is the area of the second one?

we know that

the ratio of the perimeters is equals to the scale factor

scale factor=5/8

scale factor=measure smaller square/measure larger square

let

smaller square=first square

larger square=second square

area smaller square=[scale factor]²*area larger square

so

area larger square=area smaller square/[scale factor]²

scale factor=5/8

area smaller square=225 m²

area larger square=225/[5/8]²> 225/(25/64)-- > 225*(64/25) > 576 m²

the answer is

the area of the  second square (larger square) is 576 m²

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
