Answer:
let l be x
formula of perimeter =2×(l+b)
130=2×(x+30)
130=2x+60
130-60=2x
70=2x
l=35cm
area =l×b
=35×30
=1050cm^2

GivEn :
- Breadth of Rectangle = 30 cm
- Perimeter of Rectangle = 130 cm
To find :
- Length and area of Rectangle?
Solution :
☯ Let Length of rectangle be x cm.
★ According to the Question:
- Perimeter of Rectangle = 130 cm
We know that,
• Perimeter of Rectangle = 2(length + breadth)
Therefore,
➯ 2(x + 30) = 130
➯ x + 30 = 130/2
➯ x + 30 = 65
➯ x = 65 - 30
➯ x = 35
∴ Thus, Length of rectangle is 35 cm.
⠀━━━━━━━━━━━━━━━━━━━━━━━━━
Now, Finding area of Rectangle,
As we know that,
• Area of rectangle = Length × Breadth
➯ Area = 35 × 30
➯ Area = 1050 cm².
∴ Hence, Area of rectangle is 1050 cm².
