Question

The length of a rectangle is twice of its breadth if it’s perimeter is 64 cm find the dimensions of the rectangle? And area of rectangle

Answer 1

$<h2>SOLUTIONS:</h2>$

Given:Length of rectangle is twice it's breath

So, let the breath be" X"

Then The length Will be 2X

The formula of Area of rectangle is

2(Length +Breath)

According to questions perimeter is64cm

So, 2(2X+X)=64

=>3X=64/2

=>3X=32

=>X=32/3

=>X=10.7(approximately)

Now Length is 2×10.7

=21.4cm

Breath is 10.7

Now area of rectangle is

=(LENGTH ×BREATH)

=21.4×10.7

=228.98cm^2

Answer 2

$\huge\texttt{Annyeong}$

Let the length be 2x

and

Bredth be x.

Their perimeter given = 64cm

So,

Perimeter of rectangle = 2(L+B)

64 ==> 2 (2x + x)

64==> 4x + 2x

64/6 ==> x

10. 6 = x

Length (2x)= 10.6 × 2 = 21.2

Bredth (x) = 10.6

Area = (L*B)

= 224.72
