Answer 2

$\Large \blue {\bold {⚝Given⚝}}$

Given,

• Area of rectangular plot = 340 sq.m
• Breadth of the plot = 17m

$\Large \blue {\bold {⚝To~find⚝}}$

We have to find the length and the perimeter of the rectangle.

$\Large \blue {\bold {⚝Solution⚝}}$

Let the unknown length of the rectangular plot be y.

$\sf \red {✤~~Area~of~rectangle=Length×Breadth~~✤}$

$\green \mapsto \sf y \times 17m=340 \: sq.m$

$\green \mapsto \sf y= \cfrac{340~sq.m}{17m}$

$\green \mapsto \sf y=20m$

$\sf \orange {\therefore ~The~length~of~the~rectangle~is~20cm.}$

$\sf \red {✤~Perimeter~of~rectangle=2(Length+Breadth)~✤}$

$\green \mapsto \sf 2(17m+20m)$

$\green \mapsto \sf 2(37m)$

$\green \mapsto \sf 74m$

$\sf \orange {\therefore The~perimeter~is~74m.}$
