Question

What will be the cost of wooden stick required to frame a square picture of side $\text{80 cm ?}$ The cost of wooden stick is $\text{50 paise}$ per $\text{cm.}$

Answer 1

Step 1:-

Shape of wooden stick frame is Square and whose side $\text{80 cm}$

Assume that square side is $\text{'a' cm}$

Perimeter of square $\text{= AB + BC + CD + DA}$

$\text{⇒ a + a + a + a}$

$\text{⇒ 4 a}$

$\text{⇒ 4}\left(\text{80}\right)$

Perimeter of square $\text{= 320 m}$

Step 2:-

Cost of wooden stick required for frame $\text{50 paisa}\left(\text{or}\right)\text{0.5 rupes}$ per $\text{cm}$

Total cost of wooden stick required for frame $\text{= 320 × 0.5}$

Hence the total cost of wooden stick required for frame $\text{= 160 paise}$.
