Question

A square of side 6 cm and a rectangle of breadth 4 cm have the same area. The length of the rectangle is .

• A. 12 cm
• B. 4 cm
• C. 6 cm
• D. 9 cm

Answer 1

The correct option is D 9 cm

The area of the square = $s^2$ = $6\times 6=36c{m}^2$
The area of the rectangle is $l\times b$.
Since the areas are equal $l\times b=36c{m}^2$
$l\times 4=36$
$l=36÷4=9cm$
