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 o
nata0808 [166]

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

Answer:

z = 113

y = 31

Step-by-step explanation:

j || n and line a is their transversal. (given)

Therefore,

z° = 180° - 67° (exterior angles on the same side of transversal)

z°= 113°

z = 113

(5y - 88)° = 67° (exterior alternate angles)

5y - 88 = 67

5y = 67 + 88

5y = 155

y = 155/5

y = 31
