Question

of the rectangle is
> The perimeter of a rectangle is 130 cm. If the breadth of the rest
30 cm, find its length. Also find the area of the rectangle.​

Answer 1

Step-by-step explanation:

The perimeter of rectangle =

2(l+b) = 130

= l+30 = 65

= l = 35

Area of perimeter = l×b

= 35×30

= 1050 cm

Answer 2

Given :-

• Perimeter = 130 cm
• Breadth = 30 cm

To find :-

• Length of rectangle ?
• Area of rectangle ?

Formula used :-

Perimeter = 2 (l + b)

130 cm = 2(l + 30 cm)

⇒ 1302 cm = l + 30 cm

⇒ 65 cm = l + 30 cm

⇒ 65 cm – 30 cm = l

∴ l = 35 cm

Area of the rectangle = l × b

= 35 cm × 30 cm

= 1050 ${cm}^{2}$

Perimeter and Area of Rectangle:

● The perimeter of rectangle = 2(l + b).

● Area of rectangle = l × b

● Diagonal of rectangle = √${(l}^{2}$+${b}^{2)}$

Perimeter and Area of the Square:

● Perimeter of square = 4 × S.

● Area of square = S × S.

● Diagonal of square = S√2
