Question

The area of a rectangular field whose length is twice its breadth
is 2450 m2. Find the perimeter

Answer 1

Answer:

x × 2x = 2450

2x²=2450

x²=1225

x=35

2x=70

perimeter=2(l+b)

=2(70+35)

=2×105

=210m

perimeter=210m

Answer 2

${\large{\bf{\orange{\boxed{\underline{Solution :}}}}}}</p><p>[tex]{\sf{\green{Let \: the \: length = B}}}$

${\sf{\green{Let \: Breadth = 2 \times B \: or \: 2b}}}$

${\sf{\pink{B \times 2B = 2450 {m}^{2} }}}$

${\sf{\green{ {b}^{2} = 2450m}}}$

${\sf{\green{B= \sqrt{2450m} }}}$

${\sf{\green{B= \sqrt{1225} m}}}$

${\sf{\red{\boxed{B = 35m}}}}$

Than,

${\sf{\green{Length = 2 \times B }}}$

${\sf{\green{Length = 2 \times 35 }}}$

${\sf{\red{\boxed{Length = 70m}}}}$

So,

${\orange{\tt{\boxed{Length = 35m, Breadth = 70m}}}}$
