Question

If the area of the rectangle is128cm2 and length and length is twice to breadth.find the length and breadth
​

Answer 1

Let take length as 2x and breadth as x

We are given

Area =128

128=2x×x

128= 2xsquare

128/2=xsquare

64=xsquare

16=length(2x)

And breadth = 8

The Breadth of the rectangle = b

The Length of the rectangle, l = 2b

The Area of the Rectangle, A = 128 cm^2

We know that ,

$area \: of \: rectangle \: = \times l \times b$

From this ,,,

Area , A = 2b × b

128 = 2b^2

b^2 = 64

b = 8 cm

The Length of Rectangle, l = 2b

l = 2 × 8

l = 16 cm
