Question

The perimeter of a rectangular field is 151m.if its breadth is 32m find its length & area

Answer 1

Perimeter = 2( L + B )
=> 2 ( L + 32 ) = 151
=> ( L + 32 ) = 151/2
=> L = 75.5 - 32
=> 43.5 = Length .

Area = L × B
=> 43.5 × 32
=> 1392m² = Area .

It can be a correct answer .

Answer 2

perimeter of rectangle = 2 multiplied by breadth +length
perimeter of rectangle = 2(32+ l)
151/2-32=l
43.5=length
area of rectangle = length multiplied by breadth
area of rectangle = 43.5*32
=1392 m^2 or 1.392 km^2
