Question

Q7. If the perimeter of a rectangular field is 160m and length is 50m.
Find its area.
​

Answer 1

Step-by-step explanation:

given,

perimeter of rectangle = 160m

2 ( l + b ) = 160m

2 ( 50 + b ) = 160m

100 + 2b = 160

2b = 160 - 100

2b = 60

b = 60/2

b = 30m

now,

area of rectangle = l*b

= 50*30

= 1500m²

Answer 2

Answer:

perimeter =160m

Length =50m

Perimeter Of Rectangle = 2×(l+b)

160m= 2×(50+b)

160÷2= (50+b)

80=(50+b)

b= 80-50

b= 30.

Area Of Rectangle= l×b

50×30

=1500m^2

Step-by-step explanation:

So, Area of Rectangle is 1500m^2
