A rectangle whose sides are in the ratio 6 : 5 is formed by bending a circular wire of radius 42 cm.
Question 1:
A rectangle whose sides are in the ratio 6 : 5 is formed by bending a circular wire of radius 42 cm. Find the largest side of the rectangle.
A.60 cm
B.72 cm
FeedbackLength of wire = 2ᴨr = 264 which should be equal to the perimeter of rectangle in which it is bent. So 2(6x + 5x) = 264 Solve, x= 12 Largest side = 6x = 6*12 = 72
C.78 cm
D.84 cm
