a similar question

Side of a square flower bed (s) = 1m 80 cm

= 100 cm + 80cm

= 180 cm --:(1)

According to the problem given,

enlarged width (w) = 20 cm

Side of the new square (S)

= s+2w

= 180 + 2×20

= 180+40

= 220 cm---(2)

Now ,

Area of increase in the area of the flower bed (A) = S² - s²

= (220)² - (180)²

= (220+180)(220-180)

= 400 × 40

= 16000 cm²

= 1.6 m²
