Question

18) Find the width of a rectangularvegetable garden if its perimeter is 16.4m and its length is 5 m.

please tell answer step by step...​

Answer 1

Answer:

3.2m

Step-by-step explanation:

Perimeter = 2×(L+B)

16.4 = 2×(5+B)

16.4 = 10+2B

16.4-10 = 2B

6.4 = 2B

B = 6.4÷2 = 3.2

Answer 2

➤ Given :-

Perimetre of the garden :- 16.4 metres

Length of the garden :- 5 metres

➤ To Find :-

Width of the vegetables garden.............

➤ Formula required :-

${\large \tt \dashrightarrow \orange{\boxed{\tt \gray{\dfrac{Perimetre}{2} - Length}}}}$

➤ Solution :-

Width of the vegetables garden :-

${\tt \longrightarrow \dfrac{16.4}{2} - 5}$

$\tt \longrightarrow \cancel \dfrac{16.4}{2} - 5 = \boxed{\tt 8.2 - 5}$

$\tt \longrightarrow 3.2 \sf \: \: metres$

$\Huge\therefore$ The width of the vegetables garden is 3.2 metres.
