Question

two numbers are in the ratio 5:7 and its perimeter is 90cm. the length of its largest side is? please tell fast​

Answer 1

Answer:

Length is smaller than breadth.

Step-by-step explanation:

Let length = 5x

breadth = 7x

ATS,

2(l+b) = 90 cm

2( 5x + 7x ) = 90 cm

2 ( 12x ) = 90

12x = 90/2

12x = 45

x = 45/12

x = 75/3 or 37.5

Length = 5 × 37.5 = 187.5

Breadth = 7 × 37.5 = 262.5

I hope this is helpful to you..........
