Question

find the area of rectangular whose length is thrice it's breadth where breadth is 4 x​

Answer 1

Step-by-step explanation:

Given,

Breadth, b = 4 x

Length, l = 3 × 4x = 12 x

Thus,

Area of rectangle = 4x × 12 x = 48 x²

Answer 2

$\large\bf\underline \blue {To \: \mathscr{f}ind:-}$

• we need to find the area of rectangle

$\huge\bf\underline \red{ \mathcal{S}olution:-}$

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

• Breadth of rectangle = 4x
• Length is thrice it's breadth.

So,

⇢Breadth = 4x

⇢Length = 3 × 4x

⇢Length = 12x

We know that,

$\star \pink{ \rm \: Area \: of \: rectangle = l \times b}$

⇥ Area of rectangle = 4x × 12x

⇥ Area of rectangle = 48x²

Hence,

• Area of rectangle = 48x²

⠀⠀✫Some formulas :-

⪼ Area of rectangle = l × b

⪼ Perimeter of rectangle = 2(l + b)

⪼ Length of rectangle = Area/Breadth

⪼ Breadth of rectangle = Area/length

⪼ Diagonal of rectangle = √l² + b²
