Question

If the length is 18 cm and the perimeter is 200 cm ,find the breath and also the Area of the rectangle plot

Answer 1

hii!!

here's ur answer...

given the Length of the rectangular plot is 18cm

therefore 2(l+b)=200cm

→ (18+b)=200cm

→ 18+b=200/2

→ 18+b=100

→ b=100-18

→ b=82cm

area of the rectangular plot=l×b

=18×82

=1476cm²

hope this helps..!

Answer 2

$hey \\ \\ perimeter \: of \: rectangle = 2(l + b) \\ 200cm = 2(18 + b) \\ \frac{200}{2} = 18 + b \\ 100 = 18 + b \\ 100 - 18 = b \\ 82 = b \\ \\ area \: = l \times b \\ 18 \times 82 \\ = 1476cm {}^{2}$
