Question

The perimeter of rectangle are13cm and breath is 2(3/4) what is the leanth of rectangle

Answer 1

✬ Length = 5 cm ✬

Step-by-step explanation:

Given:

• Perimeter of rectangle is 13 cm.
• Measure of breadth of rectangle is 2(3/4) cm.

To Find:

• What is the measure of breadth ?

Solution: Let the meaure of length be x cm. Therefore,

➽ Length = x cm

➽ Breadth = 2(3/4) = 6/4 = 3/2 cm

As we know that,

★ Perimeter of Rectangle = 2(Length + Breadth) ★

A/q

• Perimeter = 13 cm

$\implies{\rm }$ 13 = 2(x + 3/2)

$\implies{\rm }$ 13 = 2(2x + 3/2)

$\implies{\rm }$ 13 = 4x + 6/2

$\implies{\rm }$ 13 $\times$ 2 = 4x + 6

$\implies{\rm }$ 26 = 4x + 6

$\implies{\rm }$ 26 – 6 = 4x

$\implies{\rm }$ 20 = 4x

$\implies{\rm }$ 20/4 = x

$\implies{\rm }$ 5 = x

So, Dimensions of rectangle are

=> Length = x = 5 cm

=> Breadth = 3/2 cm

Answer 2

• Given -

The perimeter of rectangle are 13cm and breadth is 2(3/4)

• To Find -

Length of the given rectangle

• Solution -

• Let Suppose the length be x
• Breadth = 2(3/4) = 6/4 = 3/2 .. (Dividing by 2)
• Perimeter = 13m

Formula we are gonna to use is Perimeter of Rectangle,

☆ Perimeter of Rectangle = 2 ( l + b )

Placing Values According to given Conditions,

$⟹13 = 2(x + \frac{3}{2} )$

$⟹1 3 = 2(2x + \frac{3}{2} )$

$⟹13 =( 4x + \frac{6}{2} )$ .. (Multiplying 2 by 3/2 gives 6/2)

$⟹13 \times 2 = 4x + 6$ .. (Replacing values to get equal terms)

$⟹26 = 4x + 6$

$⟹4x = 26 - 6$

$⟹4x = 20$

$⟹x = \frac{\cancel{20}}{\cancel{4}}$

$⟹x = 5$

⛬ Length of rectangle is 5cm
