Question

A square and a rectangular field with measurements as given in the figure have the same perimeter. Find the width of the rectangular field.

• A. 30 m
• B. 50 m
• C. 60 m
• D. 40 m

Answer 1

The correct option is D 40 m

Pgiven that the perimeter of both the shapes are equal.

=> Perimeter of the square = Perimeter of the rectangle

=> 4 × s = 2 (l + b)

=> 4 × 60 = 2 (80 + b)

=> 240 = 160 + 2b

=> 2b = 80 m

=> b = 40 m

Hence the width of the rectangle is 40 m.
