Hi Mate!!
{ 8x } = 32
x = 4
So, length is 4 × 5 = 20
and
breadth is 4 × 3 = 12
{ 8x } = 32
x = 4
So, length is 4 × 5 = 20
and
breadth is 4 × 3 = 12

the curved surface area of a cone is 22√2cm square if the base radius is 7√2cm find out its slant height π=22/7
Curved surface area if cone = πrL, where r is base radius and L is slantheight ............. πrL = 22√2 ........... ( 22 / 7 ) × 7√2 × L = 22√2........... L = 1cm....... So, slantheight = 1 cm ......have a nyc day

5x : 3x
1/2*32=16-perimeter
16=2(5x+3x)
16=2(8x)
16=16x
x=1
therfore length =5x1=5cm
and breadth =3x1=cm.
