C-12-Q109mediumsingle_mcq

With length $x$ and breadth $y$ , the condition "twice the breadth is $10$ m more than the length" gives —

a $2y = x + 10$
b $2x = y + 10$
c $x + y = 10$
d $x - y = 10$

ব্যাখ্যা

"Twice the breadth" is $2y$ , and being " $10$ m more than the length" means it exceeds $x$ by $10$ , giving $2y = x + 10$ .
