Question

The area of a square is 1260 Sq.cm and its breadth is 20 cm . Find its length​

Answer 1

Answer:

$\sf \: let \: the \: length \: be \: x \: \\ \sf \: breadth \: of \: rectangle = 20 \: cm \: \\ \sf \: area \: of \: rectangle = 1260 \: {cm}^{2} \\ \\ \sf \red{acc. \: to \: question : - } \\ \sf \: \: length \times breadth = area \: \\ \sf \: x \times 20 = 1260 \\ \sf20x = 1260 \\ \sf \: x = \cancel \frac{1260}{20} \\ \boxed{\sf x = 63cm}$

therefore; length of rectangle is 63 cm.

hope it helps you dear...
