Answer:
3760
Step-by-step explanation:
first take length to be 3x and breadth to be 2x
now
3X×2X=1536
6X^2=1536
X=16
Now use perimeter of rectangle formula 2(l+b)=2(32+48)=160
now multiply he cost with perimeter
be safe with calculative part as you may do silly mistakes

Answer:
Cost = ₹3760
Step-by-step explanation:
Ratio of sides = 3:2
Length = 3x
Breadth = 2x
Area = l × b
= 1536 m²
3x × 2x = 1536 [ 3x × 2x = (3×2) (x×x) = 6x²]
6x² = 1536
x² = 1536/6
x² = 256
x = √256
x = 16
Check ⇒ 3x × 2x = 1536
x = 16
3 × 16 × 2 × 16 = 1536
48 × 32 = 1536
1536 = 1536
L.H.S = R.H.S
Hence, the answer is correct that x = 16.
Length = 48 m
Breadth = 32 m
Perimeter = 2[l+b]
= 2 [ 48 + 32]
= 2 × 80
= 160 m
Cost per metre = ₹23.50
Cost of 160 m = ₹23.50 × 160
= ₹3760
