i) perimeter
ii)area


pls. help me to solve with solution this I ll be thankful to you​

Answer 1

Step-by-step explanation:

The rectangular sheet is 10$\frac{2}{3}$ cm wide, 12$\frac{1}{2}$ long.

So, the perimeter of a rectangle can be found by using the formula 2(l+w)

= 2(12$\frac{1}{2}$+10$\frac{2}{3}$ )

= 2($\frac{25}{2}$+$\frac{32}{3}$)

= 2($\frac{75+64}{6}$)

= 2($\frac{139}{6}$)

= $\frac{139}{3}$

= 46$\frac{1}{3}$

So, this is the perimeter

Now the area of a rectangle can be found by formula (lxb)

= 12$\frac{1}{2}$ x 10$\frac{2}{3}$

= $\frac{25}{2}$ x $\frac{32}{3}$

= 133$\frac{1}{3}$

And that's the area
