Answer:
A = 10.27cm²
Step-by-step explanation:
Let's represent the width as x, 
therefore since the length is 4 more than 3 times the width, it can be represent as 3x + 4,   Perimeter = 18.4cm
Perimeter of a rectangle = 2(L + B)

width = 1.3cm
Length = 3x + 4 = 3*1.3 + 4 = 7.9cm
Area of a rectangle = length x width
A = 7.9 * 1.3 = 10.27cm²

Answer:
the side of a square is 45 m
Step-by-step explanation:
The computation of the side of the square field that contains the similar area as compared with rhombus is given below:
As we know that
Area of rhombus = Base × Altitude
= 81 × 25
= 2025
And, area of Square =  Side × side
2025 = side^2
side  = √2025
= 45m
Hence, the side of a square is 45 m
