Question

The perimeter of a rectangle is 58m .if its length is 17m finds its breadth (give step by step explanation)​

Answer 1

$\bigstar$ Question :

$\longrightarrow$ The perimeter of a rectangle is 58m. If its length is 17m.find its breadth.

$\bigstar$ To Find :

$\longrightarrow$ Breadth of rectangle = ?

$\bigstar$ Given :

$\longrightarrow$ Perimeter = 58m

$\longrightarrow$ Length = 17m

$\bigstar$ Required Formula :

$\longrightarrow$ Perimeter of rectangle = 2(l + b)

$\bigstar$ Solution :

$\longrightarrow$ 58 = 2(17 + b)

$\longrightarrow$ 58 = 34 + 2b

$\longrightarrow$ 58 - 34 = 2b

$\longrightarrow$ 24 = 2b

$\longrightarrow$ b = 24 ÷ 2

$\longrightarrow$ b = 12

Therefore,The breadth of rectangle is 12m.

Let us verify that,

$\longrightarrow$ Perimeter of rectangle = 2(17 + 12)

$\longrightarrow$ Perimeter of rectangle = 2(29)

$\longrightarrow$ Perimeter of rectangle = 58m

Hence,Verified.
