Question

Two fields have same perimeter one is a square of side 72m and another is a rectangle of length 80m which field has the greater areaand by how much

Answer 1

perimeter of square is 288
2 (80+b)=288
80+b=144
b=64
Area of rectangle=lb=80×64=5120
Area of square =a^2=72^2=5184
Area of square is greater than area of rectangle by 64m

Answer 2

$\bf\huge\boxed{\boxed{\bf\:Hello\:Mate}}}$

According to the Question

Given

Perimeter is Same

Hence

2 (80 + b) = 288

80 + b = 144

b = 64

Area of rectangle = length × breadth

= 80 × 64

= 5120

Area of square = Side^2

= (72)^2 = 5184

Area of square is (>) than area of rectangle
