Question

The length of rectangular field is twice it's length . If the perimeter is 150m. Find its length and breadth

Answer 1

Answer:

Step-by-step explanation:

Please mark as brainliest

LET THE QUANTITIES BE X

LENGTH = 2XM

BREADTH =XM

PERIMETER = 150M

WE KNOW PERIMETER OF A RECTANGLE = 2×(L+B)

2×(2X+X)=150

2×3X = 150

6X = 150

X = 150÷6

X = 25

LENGTH =2X=2×25 = 50M

BREADTH=X=25 M .

VERTIFIED DOWN

2×(L+B)=150

2×(50+25)=150

2×75=150

150=150(PROVED)

Answer 2

L=2b

perimeter = 2(l+b)

150=2(2b+b)

b=25m
