Question

The perimeter of a rectangular field is 120m and the difference between its two adjacent sides is 30m. the sides of the square field whose area is equal to this rectangular field is?​

Answer 1

Answer:

Let one side be =x

Let another side be= x+30

perimeter of rectangle =2(l+b)

120=2(x+x+30)

120/2=2x+30

60-30=2x

30/2=x

x=15

therefore 2 sidea are 15 and 45

area of rectangle=l×b

=15×45

675

therefore side of a square = root675
