Question

Family photograph has length $14\frac{2}{5}$ cm and breadth $10\frac{2}{5}$ cm. It has border of uniform width $2\frac{3}{5}$ cm. Find the area of framed photograph?

Answer 1

Length of the photograph $=14\frac{2}{5}=\frac{72}{5}$cm
Width of the border $2\frac{3}{5}=\frac{13}{5}$ cm

Length of the framed photograph $=\frac{72}{5}+2\times \frac{13}{5}=\frac{98}{5}$ cm

Breadth of the photograph $=10\frac{2}{5}=\frac{52}{5}$

Breadth of the framed photograph $=\frac{52}{5}+2\times \frac{13}{5}=\frac{78}{5}$ cm

Area of the framed photograph $=\frac{98}{5}\times \frac{78}{5}=\frac{7644}{25}c{m}^2$
