Question

A thin wire 50cm long is form into a Rectangle If the length of this Rectangle is 15cm what is its breadth Find the area of Rectangle also​

Answer 1

Answer:

Breadth = 10 cm
Area = 150 $cm^{2}$

Step-by-step explanation:

Perimeter of rectangle = 2(l + b) = 50
length = 15 cm
2(15 + b) = 50
15 + b = 50/2 = 25
b = 25 - 15 = 10
b = 10 cm

Area of rectangle = l*b

⇒ 15 * 10 = 150 $cm^{2}$

Answer 2

$Perimeter \: of \: Rectangle \\ = 2 ( length + Breadth)$

$50 = 2(15 +Breadth)$

$\frac{50}{2} = 15 + Breadth$

$25 = 15 + Breadth$

$25 - 15 = Breadth$

$10 = Breadth$

$Area\: of \: Rectangle \\ = ( length + Breadth)$

$Area\: of \: Rectangle \\ = (15 × 10)$

$Area\: of \: Rectangle = \\ 150$
