Question

Find the length of a rectangular field of width 75 metre and perimeter 360 m.​

Answer 1

Answer:

perimeter of rectangle = 2×(l+b)

360 = 2(75+L)

360= 150 +2L

2L = 360-150

2L = 210

L = 105

so ,

length = 105 m

Answer 2

perimeter of rectangle-:

2(l+b)

2(l + 75 ) = 360

l + 75 = 360 / 2

l + 75 = 180

l = 180 - 75

l = 105 m
