Question

12. The ratio b/w length & breadth of a rectangular plot
71:61. Area of plot is 17324sq.m. Find its perimeter?

Answer 1

Answer:

LET RATIOS BE=71x and 61x

area=17324sq.m

l*b=17324

71x*16x=17324

4331x2=17324

x2=17324/4331

x2=4

x=√4

x=2

length=71*2=142

breadth=61*2=122

perimeter=2(l+b)

=2(142+122)

=2*264

=528m
