hey mate here is your answer.
let the breath be of x unit
therefore, length = 2x unit
A/Q
c.s.a. of cylinder =1215 square unit
c.s.a is form from a rectangular mettalic sheet
therefore, area of rectangular metallic sheet = c.s.a of cylindder
length × breath = 1215
2x×x=1215
2x^2=1215
x^2=1215÷2
x^2=607.50
x=24.64 square unit
x=breath=24.64 unit
the length =49.28 unit
so, the dimension of the rectangular sheet =49.28 unit × 24.64 unit
hope it helps you.
