Question

find the lenght of the wooden strip required to frame a photograph whose lenght is 6.2 m and 5.9 cm respectively.​

Answer 1

Answer :

24.2 m

Step-by-step explanation:

Given :

• Length = 6.2 m

• Breadth = 5.9 m

To find the length of wooden strip to frame this photograph, firstly we have to find the perimeter of photograph.

${\underline{\boxed{\bf{Perimeter \: of \: Rectangle \: = 2 \times (l + b)}}}}$

• l = 6.2
• b = 5.9

$\rightarrow \sf 2 \times (l + b) \\ \\ \sf \rightarrow 2 \times( 6.2 + 5.9) \\ \\ \rightarrow \sf \: 2 \times 12.1 \\ \\ \rightarrow \bf 24.2$

So, Perimeter of Rectangular photograph is 24.2 m.

Hence,

Since the perimeter is 24.2 m then, the length of wooden strip needed to frame is also 24.2 m

∴ Length of wooden strip = 24.2 m
