- Option E None of these
Let the breadth is x
and length=20+x
Perimeter=5300/26.50=200
x+20+x=200
2x=180
x=90
length =20+90=110 - 12 years agoHelpfull: Yes(2) No(2)
- Option E NONE OF THESE
Let the breadth is x
and length=20+x
Perimeter=5300/26.50=200
2(x+20+x)=200
2x+20=100
x=40
length =20+40=60

- perimeter formula is2(l+b)
2(x+x+20)=200
4x+40=200
4x=160 - 9 years agoHelpfull: Yes(1) No(0)
- option e
breadth=x
length=x+20
perimeter=5300/26.50=200
perimeter=2(length+breadth)
2(x+20+x)=200
4x+40=200
x=160/4
x=40
length=40+20=60
