160
l+10=80
l=80−10
l=70m
Area:
\begin{gathered} = l \times b \\ \\ = 70 \times 10 \\ \\ = 700 \: {m}^{2} \\ \\ \end{gathered}
=l×b
=70×10
=700m

Answer:
Perimeter = 2(l+b)
According to the question,
Perimeter = 160m
Perimeter = 160mWide (or breath) = 10m
Puting both
160 = 2( l+10)
160÷2 = l +10
80 = l+10
80-10 = l
l ( or length ) = 70m.
Area of rectangle = length × breath
Area = 70 ×10
Area = 700m²
Therefore, area of rectangle is 700m²
