Question

The length of rectangular field is 3 times its breadth. If the area of the field is 147 sq. m. find its length.

Answer 1

Let the breadth of the rectangular field be x. Then, the length is 3x.

It is given that the area of the field is 147 sq. m.

Here, x = –7 is not valid as x is the breadth.

∴Length = 3x = 3 × 7 m = 21 m
