Question

4. Find the distance covered by a boy going round once
a rectangular garden 45 m long and 35 m wide-
(A) 145 m
(B) 135 m
(C) 100 m
(D) 160 m​

Answer 1

Answer:

D)160

Step-by-step explanation:

It shows perimeter so

Perimeter of a rectangle = 2(l+b)

= 2(45+35)m = 2×80=160m

Answer 2

${ \bf{ \red{ \underline{ \purple{ \underline{Given \: data}}}}}:-}$

◐ A rectangular garden 45m long and 35m wide.

${ \bf{ \red{ \underline{ \purple{ \underline{Solution}}}}}:-}$

◐ We also know that opposite sides of rectangle are equal ( of equal length ).

◐ Let, length ( L ) of rectangular garden 45m. and breadth ( B ) of rectangular garden 35m.

Now we use formula of permiter of rectangle.

→ Perimeter of rectangle = 2 × ( L + B )

→ Perimeter of rectangle = 2 × ( 45 + 35 )

→ Perimeter of rectangle = 2 × 80

→ Perimeter of rectangle = 160 m

Hence, answer is option ( D ) 160 m. or

Hence, the distance covered by a boy is 160 m.
