Question

find the perimeter of rectangular sheet is 100 cm if the length 15.35 cm find its area​

Answer 1

=>perimeter of rec. = 2(l+b)

=>100 =2( 15.35 +b)

=> 100 - 2( 15.35) = 2b

=> 100- 30. 70 = 2b

=> 69 .30/2 = b

=> 34.65 is breadth.

then area of rec. = l×b

=> = 15.35 × 34.65

solve it and get ur answer

Answer 2

HERE IS YOUR ANS.

PERIMETER of rectangular sheet

:- 2(l+b)

given :- perimeter = 100cm

so, 2(l+b) = 100

l+b = 50

given :- l =15.35

so , b = 50+15.35 = 34.65cm

now, Area = l×b

= 15.35×34.65 =531.8775 cm ² ans.
