Answer 1

Answer:

Length of diagonal is 37 cm

Step-by-step explanation:

AB^2+BC^2=AC^2

35^2+12^2=AC^2

1225+144=AC^2

1369=AC^2

AC=sqrt1369

AC=37

Answer 2

$[sol]\\given\\length, l=35 cm\\breadth, b=12 cm\\\\Find- diagonal of rectangle\\\\d^{2} = l^{2} +b^{2} \\=>35^{2} +12^{2} \\=>1225+144\\=>1369\\now\\d^{2} =1369cm^{2}\\d=\sqrt{1369}\\d= 37$
