Answer:
The length of one plot is 45m & the other length is 25m
Step-by-step explanation:
Let length one sq. plot = x length other sq. plot = y
area of square = length²
x² + y² = 2650 -----(1)
x² - y² = 1400 ------(2)
(1)+(2)
2x² = 4050
x² = 2025
x = 45
subx²=2025into(1)
2025 + y² = 2650
y² = 625
y = 25
