Question

A. same and a rectangular field with measurment our given in the figures below have same perimeter . which field has larger area? square is of 45m and rectangle of 60m

Answer 1

Side of square = 45 m

Length of rectangle = 60 m

According to question,

Perimeter of square = Perimeter of rectangle

=> 4 × 45 = 2( 60 + Breadth)

=> 90 = 60 + Breadth

=> Breadth of rectangle = 30 m

Now,

Area of square = 45 × 45 = 2025 m^2


Area of rectangle = 60 × 30 = 1800 m^2

So,

Square field has more Area.

Answer 2

Answer:

60 = side of square.

80 m = Length.

= 2 ( l + b) = 4 side.

= 2 ( 80 + b) = 4 × 60

= 160 + 2b = 240

= b = 40

40 m = Breath.

= (60)2 = 3600 m²

= L × B = [ 80 × 40 ]

= 3200 m²

.•. Area of square field is larger.
