Question

find the missing value P = 264 length = ? breadth = 20​

Answer 1

Step-by-step explanation:

Let the length be x.

Breadth=20

Perimeter =2(l+b)

264 =2(x+20)

264/2. =x+20

132. =x+20

132-20. =x

Therefore, x=112.

Answer 2

Find the missing value ....

Perimeter =. 264

Length = ????

Breadth = 20

_______________________

Solution-

$\boxed{perimeter \: of \: rectangle \: = > 2(l + b)}$

$264 = > 2(l + 20) \\ \\ \frac{264}{2} = > l +20 \\ \\ 132 = > l + 20 \\ \\ 132 - 20 = l \\ \\ \boxed{ l = > > 112}$

The length of rectangle is 112 ...

Some other important formula

✨Area of square => Side x side

✨Area of reactangle => Length x breadth

✨ Perimeter of square => 4 (side)

✨ Perimeter of rectangle => 2(l+b)
