4. A square table of side 90 cm has a frame of widtin 3 cm around it. Find the outer areas of the table and the area of the frame.

$\mathfrak{\huge \underline{Given:}}$

Length of sides= 90cm

Border width=3cm

Length of sides including Border= 90+ (3x2)=96cm

$\mathfrak{\huge \underline{Solution:}}$

We have,

Border Area = Outer Area - Inner Area

$Outer~Area ~=~ 96 cm \times 96cm =96^2cm^2= 9216cm^2 \\\\ Inner Area~=~90cm\times 90cm = 90^2 cm^2 =8100cm^2 \\\\ Border Area= 9216-8100 cm^2 =1116cm^2$

$\boxed{\bf{Outer~Area= 9216cm^2~Border~ Area= 1116cm^2}}$
