Question

The perimeter of a rectangular field is 151 m.If its breadth is 32 m, find its length and area.​

Answer 1

Step-by-step explanation:

Perimeter =2(l+b)

151=2(l+32)

151=2l+32

2l=151-32

l=119/2

l=59.5m^2

Area =l×b

=59.5×32

=1904m^2

Answer 2

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
