A rectangular field has a perimeter of 92 m and its length is 25 m. Find the area of the field ?

(a) 640m²

(b) 21m²

(c) 525 m²

(d) 65 m²

Best Answer

(c) Perimeter = 92 m , Length = 25 m,

Let breadth = x m

P = 2 (l +b)

92 = 2 (25 + x) = 50 + 2x

2x = 92 – 50 = 42

x=42/2=21m

So, Length=25m , Breadth=21m

Area 25*21=525m²
