| Answer» QUESTION :-The perimeter of a RECTANGULAR sheet is 70 cm. If its breadth is 15 cm, Find its area.Answer :-The area of rectangle is 300cm²Solution :-Given that,The perimeter of Rectangular sheet = 70cmBreadth of the sheet = 15cmFirst we need to find out the length of rectangle, and we can find it by applying the FORMULA of perimeter of rectangle,As we know that,Perimeter of rectangle = 2 ( Length + Breadth ),=> 2 ( Length + 15 ) = 70=> Length + 15 = 70/2=> Length + 15 = 35=> Length = 35 - 15=> Length = 20The length of rectangle is 20cm.According the question,The area of rectangle is,As we know that,Area of rectangle = Length × Breadth,THEREFORE,=> Area = 20cm × 15cm=> Area = 300cm²The area of rectangle is 300cm². | |
