Question

The perimeter of a rectangular field is 151 M if its breadth is 32 M find its length and area

Answer 1

P= 151m

151=2(l+b)

=2(l+32)

151/2=l+32

75.5-32=l

43.5m=l

Area=l*b

= 43.5*32

=1392M²

Answer 2

Step-by-step explanation:

Perimeter = 151 m

Breadth = 32 m

Length =

$\frac{perimeter }{2} - breadth \\ \frac{151}{2} - 32 \\ = \frac{87}{2} = 43.5m$

Area = l×b = 32 × 43.5m² = 1392 m²
