Answer 1

20m * 7m.

Explanation:

The area of the yellow rectangle = 14*10 = 140m^2 = the area of the brown one.

The perimeter of the brown one = 54 so

2L + 2W = 54

L + W = 27

and LW = 140

L = 140/W

140/W + W = 27

140 + W^2 = 27W

W^2 - 27W + 140 = 0

W = 20,7

and L = 140/W = 7,20

Length = 20, width = 7.
