the sides; find the area of the frame?​

Answer 1

Answer:

            406sq.cm

Step-by-step explanation:

total length of picture=25+2+2=29cm

total breadth of picture=10+2+2=14cm

area of picture=length*breadth

                        =29*14

                        =406sq.cm

Answer 2

Step-by-step explanation:

length of picture =25cm

breadth of picture=10cm

area of picture=l×b

=25×10

=250cm²

length of picture with frame=25+(2+2)=25+4=29cm

breadth of picture with frame=10+(2+2)=10+4=14cm

area of picture with frame=l×b=29×14=406cm²

area of frame=area of picture with frame- area of picture

=406-250=156cm²
