Question

family photography has length 24 and2/5 cm and breadth 20 and 2/5 cm it has border of uniform width 3 and 3/5 cm find the areaof the framed photography

Answer 1

The border will be on both sides of the length and the breadth

The length and the breadth will increase by twice the width of the border

= 2 x 3(3/5) = 36/5

Length of framed photograph = 24(2/5) + 36/5 = 158/5

Breadth of framed photograph = 20(2/5) + 36/5 = 138/5

Area of the framed photograph = 158/5 x 138/5

                                                  = 872 and 4/25

                                                  = 872.16 cm²
