Question

length=?,breath=50mm,area=?,perimeter=300mm​

Answer 1

Answer:

Perimeter = 300mm

2 ( l + b ) = 300

2 ( l + 50 ) = 300

2l + 100 = 300

l = 300-100/2 = 300 - 50 = 250mm

Area = l x b

250 x 50 = 12500mm^2

Answer 2

Step-by-step explanation:

Perimeter=2(l+b)

300. =2(l+50)

300. =2l+100

300-100=2l

200./2. =l

100. =l

now,area =l*b

=100*50

=5000mm
