Given:-

• Side of the flower bed = 380cm
• It is extended by 50cm all around

To Find:-

• Area of the enlarged flower bed
• Area of the increase in size of the flower bed

Calculations:-

Increased length,

= 380cm + 50cm

= 430cm

Area of the enlarged flower bed,

= 430cm × 430cm

= 184900cm²

Area of the original flower bed,

= 380cm × 380cm

= 144400cm²

Area of the increased size of the flower bed,

= 184900cm² - 144400cm²

= 40500cm²

Final Answer:-

$\huge\mathtt{40500cm²}$

Increased leangth

=380ᴄᴍ + 50ᴄᴍ

=430ᴄᴍ

Area of enlarged flower bed.

=430cm×430cm

=184900ᴄᴍ²

Area of orginal bed.

=380ᴄᴍ×380ᴄᴍ

=14400ᴄᴍ²

area of increased size of the

flower bed.

=184900ᴄᴍ² - 14400ᴄᴍ²

=40500ᴄᴍ²
