Question

यदि किसी आयत की लम्बाई तीन गुनी और चौड़ाई चार गुनी कर दी जाय तो क्षेत्रफल कितना गुना हो जायेगा?​

Answer 1

Area of a rectangle is =length*breadth square units.

If length and breadth are tripled the area becomes

= 3*length x 4*breadth

= 12*length*breadth

= 12 times the original area.

The area increases 12 times.
