Question

If the ratio of the sides of a rectangle made by turning a 42 cm long circular
wire is 5:6, what will be the length of the shorter side of the rectangle?
(a) 11.54 cm (b) 9.54 cm
(c) 10.54 cm (d) 12.54 cm​

Answer 1

Step-by-step explanation:

perimeter of a rectangle= 2(l+b)

42= 2(5x+6x)

11x=21

x= 21/11

5x= (21/11)×5

x= 105/11

x= 9.54 cm

Answer 2

Answer:

Perimeter of rectangle=perimeter of circle

2×side=2πr

22x2=132

6=x

30= 6×5
