Question

Family photograph has length 14 2/5 cm and breadth 10 2/5 cm . It has border of uniform width 2 3/5 cm. Find the area of framed photograph .

Answer 1

Answer:

Area of framed photograph is 221 cm² .

Step-by-step explanation:

Formula

Area of a rectangle = Length × Breadth

As given

$Family\ photograph\ has\ length\ 14 \frac{2}{5}\ cm\ and\ breadth\ 10 \frac{2}{5}\ cm .$

i.e

$Family\ photograph\ has\ length\ \frac{72}{5}\ cm\ and\ breadth\ \frac{52}{5}\ cm .$

$It\ has\ border\ of\ uniform\ width\ 2 \frac{3}{5}\ cm.$

i.e

$It\ has\ border\ of\ uniform\ width\ \frac{13}{5}\ cm.$

Thus

$Length = \frac{72}{5} + \frac{13}{5}$

$Length = \frac{72+13}{5}$

$Length = \frac{85}{5}$

Length = 17 cm

$Breadth = \frac{52}{5} + \frac{13}{5}$

$Length = \frac{52+13}{5}$

$Length = \frac{65}{5}$

Length = 13 cm

Area of a framed photograph = 17 × 13

                                                 = 221 cm ²

Therefore the area of framed photograph is 221 cm² .
