Question

The perimeter of a rectangle is 15cm and the length is 3cm more than the breadth. Which equation for the following equations represent the given data 1 point 2x+4=15 4x+6=15 x+3=15 x+6=15​

Answer 1

Answer:

Given that,

Perimeter of rectangular swimming pool = 154 m

Let the breadth of rectangle be = x

According to the question,

Length of the rectangle = 2x + 2

We know that,

Perimeter = 2(length + breadth)

⇒ 2(2x + 2 + x) = 154 m

⇒ 2(3x + 2) = 154

\begin{array}{l} \Rightarrow 3 x+2=\frac{154}{2} \\ \Rightarrow 3 x=77-2 \\ \Rightarrow x=\frac{75}{3} \end{array}

⇒3x+2=

2

154

⇒3x=77−2

⇒x=

3

75

⇒ x = 25 m

∴,Breadth = x = 25 m

Length = 2x + 2

= (2×25)+2

= 50 + 2

= 52 m

Answer 2

Answer:

let the breadth be 'x'

Step-by-step explanation:

According to the question , the equation will be -

x+3=15
