Question

50mm breath 300mm perimeters what is the lenth and area?​

Answer 1

Step-by-step explanation:

Perimeter=2(l+b)

300=2(50+l)

300=100+2l

300-100=2l

200=2l

2l=200

l=200/2

l=100

length=100mm

area=l*b

area=100*50

area=5000 square mm

Answer 2

Length = 2(l+b) = Perimeter

2(l+50) = 300

2l+100 = 300

2l = 300-100

2l = 200

l = 200÷2

l = 100

Area = Length*Breath

= 100x50

= 5000mm
