Question

if the length of a rectangle is always greater than breadth what will be the length of breadth if the area of the rectangle is 72 CM square and one side is 8cm long​

Answer 1

Step-by-step explanation:

Qiven Area of the rectangle - 72 cm²

Length - 8 cm

breadth = (area/length) cm²

= ( 72/8) cm

Breadth = 9 cm

Answer 2

Step-by-step explanation:

$\bf{\underline{\underline\red{Given:-}}}$

• The length of the rectangle is always greater than its breadth.

• The area of the rectangle = 72cm².

• One side of the rectangle is 8cm long.

$\bf{\underline{\underline\blue{To\:Find:-}}}$

• The length and breadth of the rectangle.

$\bf{\underline{\underline\green{Solution:-}}}$

As we know that:-

Area of rectangle is given by the formula:-

$\boxed{ \rm Area \: of \: rectangle = length \times breadth}$

Given:-

One side = 8cm

Let the other side be x

Area = 8 × x

Given; Area = 72cm²

So:-

$\rm\implies 72 = 8\times x$

$\rm\implies \dfrac{72}{8} = x$

$\rm\implies 9 = x$

The measure of other side = 9cm

According to the question

Length > Breadth

So:-

⇛ Length = 9cm

⇛ Breadth = 8cm
