Question

The width of a rectangular field is 45m. The length of
the field is twice the width Ares of the field will
be​

Answer 1

Answer:

Let the breadth (b) of the rectangular field be x

∴length(l)=2x

As we know that, perimeter of rectangle (P) is given as-

P=2(l+b)

⇒P=2(2x+x)

⇒P=2(3x)

⇒P=6x

Given that perimeter (P) of the rectangular field is 60m

∴6x=60

⇒x=

6

60

=10m

Therefore,

Breadt of the field =10m

Length of the field =2×10=20m

Answer 2

Answer:

Width =45m

Length= 45×2= 90m

$\color{black}\boxed{\colorbox{saffron}{Area - length×breadth}}$

$90 \times 45 \\ \\ = {4050m}^{2}$
