Question

find the length of rectangle

Answer 1

Perimeter of rectangle=2(l+b)
                                  =2(6.5+3.2)
                                  =2(9.7)
                                  =19.4

∴Perimeter of rectangle is 19.4m

Answer 2

Given :

• The Length and the Breadth of Rectangle

To find :

• We have to find the Perimeter of Rectangle

Formula :

$\;\boxed{\sf{\purple{Perimeter{\:(rectangle)} = 2 \: \times Length + Breadth}}}$

Solution :

$\sf a) \: Length\rightarrow 6.5 m \: Breadth \rightarrow 3.2m \\ \\ \\ : \implies \sf 2 \times (6.5 + 3.2)m \\ \\ \\ : \implies \sf 2 \times 9.7m \\ \\ \\ \: \: \: \: \: \: \: \: : \implies { \underline{ \boxed{ \pink{ \mathfrak{19.4 \: m}}}}} \\ \\ \\ \sf b) \: Length\rightarrow 4.8 mm \: Breadth \rightarrow 3.4mm \\ \\ \\ : \implies \sf 2 \times (4.8 + 3.4)mm \\ \\ \\ : \implies \sf 2 \times 8.2mm \\ \\ \\ \: \: \: \: \: \: \: \: \: \: \: : \implies{ \underline{ \boxed{ \pink{ \mathfrak{16.4 \: mm}}}}} \\ \\ \\ \sf c) \: Length\rightarrow 720 cm \: Breadth \rightarrow 640cm \\ \\ \\ : \implies \sf 2 \times (720 + 640)cm \\ \\ \\ : \implies \sf 2 \times 1360cm \\ \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: : \implies { \underline{ \boxed{ \pink{ \mathfrak{2720 \: cm}}}}}$

•°• Hence, verified!
