Question

The perimeter of the rectangle is 350cm .It's length is 120cm.Its area is​

Answer 1

Answer:

p=350

2(l+b)

2(l+b)=P

2×(120+x)=350

120+x=350/2

x=175-120

x=55

120×55

6600cm²

Answer 2

GiveN :-

• Perimeter of rectangle = 350 cm

• Length of rectangle = 120 cm

To FinD :-

• Area of the rectangle

SolutioN :-

Firstly we have to find breadth of rectangle

$\large \longrightarrow\sf Perimeter _{rectangle} = 2(L+B) \\ \\\longrightarrow\sf350 = 2(120 + B) \\ \\ \longrightarrow\sf120 + B = 175 \\ \\ \longrightarrow\sf B = 175 - 120 \\ \\ \longrightarrow\sf B = 55$

Breadth of rectangle is 55 cm , now

$\large \longrightarrow \sf Area_{rectangle} = L \times B \\ \\\longrightarrow \sf Area_{rectangle} = 120 \times 55 \\ \\\longrightarrow \boxed{ \blue{\sf Area_{rectangle} = 6600 \: {cm}^{2}}}$
