Question

what is the length of the wodden strip required to frame a photograph of length and breadth 32cm and 21 respectively?

Answer 1

to find the length of wooden strip we have to find perimeter of photograph so
p = 2(l+b)
p= 2 ( 32 + 21)
p = 2×52
p = 104
so the length of required wooden strip = 104

Answer 2

Answer-To find the length of wooden strip, we need to find the perimeter of photograph which is in the shape of rectangle.
P of photo= 2(l+b)
                = 2(32+21) cm
                = 2× 53 cm
                = 106 cm
So, length of wooden strip= 106 cm
