Question

the length of a rectangular field is twice its breadth. the perimeter of the field is 150m. whats the dimension of the rectangle

Answer 1

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)

$\huge{\pink{\implies{\boxed{\mathfrak{Answer \: is}}}}}$

$\large{\underline{\textsf{\blue{ Given}}}}$
$<b><i>$Let the breadth be x

Then,

Length=2x

Perimeter=150m

2(l+b)=150m

2(x+2x)=150

3x=150/2

3x=75

x=75/3

x=25m

Thus,
Length =(2x) =(2×25) =50m
Breadth =x=25m
