Question

7. One square and one rectangular field have the same perimeter. Which
field has a larger area??​

Answer 1

Answer:

square field

Step-by-step explanation:

Perimeter of square=4x80=320

Perimeter of rectangle=2(l+b)

320=2(l+70)

l+70=320/2

l=160-70

l=90

area of square=80x80

=6400

area of rectangle =70x90

=6300

area of square>area of rectangle

please mark it as brainliest

Answer 2

Same perimeter of both rectangle and square.

Same perimeter of both rectangle and square.Therefore, Perimeter of square = Perimeter of rectangle.

Perimeter of rectangle = 2(l + b)

4a = 2(l + b) --------(same perimeter)

4 * 80 / 2 = l + 70

160 - 70 = l

l = 90m

Area of square = a²

= (80)²

= 6400m²

Area of rectangle = l * b

= 90 * 70

= 6300m²

Hence Area of square is greater than Area of rectangle.
