Find the perimeter of a rectangle whose sides are:(a) 5 m and 3 m (b) 10 m and 8 m (c) 58 cm and 2.2 cm (d) 5cm and 3cm |

Answer» a) 2(5+3)=2*8=16mb) 2(10+8)=2*18=36mc) 2(5.8+2.2)=2(8)=16md) 2(5.5+3.5)=2(9)=18m (a)given length=5mbreadth=3m then formula for perimeter of rectangle is 2(L+B) so we have both length and breadth then 2(5+3) =2×8 =16msquare therefore perimeter of rectangle is 16m square now similarly you can solve other b c and d. |
