Question

if the perimeter of rectangle is 48 and breadth is 6 cm then it is breadth is what​

Answer 1

Correct Question

• If the perimeter of rectangle is 48 and breadth is 6 cm. Then find the length.

⠀

Given

• Breadth of the rectangle is 6cm.
• Perimeter of the rectangle is 48cm.

⠀

To find

• Length of the rectangle.

⠀

Solution

• In this question, perimeter of rectangle is used.

⠀

☆ Perimeter = 2(l + b)

⠀

→ Perimeter = 48

⠀

→ 2(l + b) = 48

⠀

→ 2(l + 6) = 48

⠀

→ l + 6 = 48/2

⠀

→ l + 6 = 24

⠀

→ l = 24 - 6

⠀

→ l = 18

⠀

Hence,

• Length of the rectangle is 18cm.

Answer 2

$\mathfrak{ \large{ \blue{ \underline{ \pink{Correct \: question: }}}}}$

If the perimeter of rectangle is 48 cm and breadth is 6 cm then what is the length of rectangle?

$\mathfrak{ \blue{ \large{ \underline{ \pink{ To \: Find: }}}}}$

• Length of rectangle

$\mathfrak{ \blue{ \large{ \underline{ \pink{Solution: }}}}}$

• Perimeter of the rectangle = 48 cm
• Breadth of rectangle = 6 cm

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathfrak{ \underline{ \green{ Formula \: to \: calculate\: the \: perimeter \: of \: rectangle}}}$

$\boxed{ \boxed{ \mathfrak {\red {\large{ perimeter = 2(length + breadth)}}}}}$

According to question,

$\large{ \sf \implies \: \: \: \: \: \: \: \: \: \: \: 2(6 + l )= 48}$

$\large{ \sf \implies \: \: \: \: \: \: \: \: \: \: \: 6 + bl= \frac{48}{2} }$

$\large{ \sf \implies \: \: \: \: \: \: \: \: \: \: \: 6 + l = 24}$

$\large{ \sf \implies \: \: \: \: \: \: \: \: \: \: \: l = 24 - 6}$

$\large{ \sf \implies \: \: \: \: \: \: \: \: \: \: \boxed{ \tt {\purple {l = 18}}}}$

$\mathfrak{ \blue{ \underline{ \pink{ \large {Hence:}}}}}$

• The length of rectangle is 18 cm.
