Question

A The length of a field is twice its breadth ; another field which
is 50 metres longer and 10 metres broader, contains 6800 square metres
more than the former ; find the size of each.
​

Answer 1

Answer:

Let the length and breadth of the rectangle be 2x m and x m, respectively.

According to the question:

2x×x=288

⇒2x

2

=288

⇒x

2

=144

⇒x=12 or x=−12

⇒x=12 (∵x cannot be negative)

∴ Length =2×12=24m

Breadth=12m
