Question

Sai needs to frame all around a rectangular board ,4 m and 150 cm wide. Find the length of frame required by Sai​

Answer 1

Answer:

The Length of the frame required is 11 m.

Step-by-step explanation:

Given :

Dimensions of the rectangle = 4 m × 150 cm

To find :

The length of the frame required all around the board

Solution :

To get the Length of the frame, the Perimeter of the rectangle should be solved.

★ $\textsf{\underline{\underline{Convert 150 cm into m : }}}$

$\sf{\implies} \: \dfrac{150}{100} \\ \\ \sf{\implies} \: 1.5 \: m$

$\rule{300}{1.5}$

$\sf{Perimeter= \purple{2(Length+Breadth)}}$

$\sf{\implies} \: 2(4 + 1.5) \\ \\ \sf{\implies} \: 8 + 3 \\ \\ \sf{\implies} \: 11$

Perimeter = 11 m

$\therefore$ The Length of the frame required is 11 m.

Answer 2

Answer:

$\bold\red{Length=11\:m}$

_________________________

Given that,

Length = 4m

Width = 150 cm

To find,

Length of the frame required.

_________________________

Length = 4m = (4 × 100)= 400 cm

Width = 150 cm

Perimeter = 2(length + width)

=> Perimeter = 2(400+150) cm

=> Perimeter = (2 × 550) cm

=> Perimeter = 1100 cm

=> Perimeter = (1100/100) m

=> Perimeter = 11 m

Length of the frame required =11 m
