Question

length and breath of the rectangle is in the ratio of 8:3 f the total area of the rectangle is 96 sq cms then what is the length of the rectangle?

Answer 1

let the ratio of length be 8x+
the area of rectangle=96
8x=96
8x=96
x=96÷8
x=12

Answer 2

Sides of the rectangle in the ratio = 8:3

Area = l×b =

$96 \: sq \: cm$

Let length be =8x

Breadth be = 3x

$8x \: \times 3x = 96$

$24x = 96$

$x = 4$

$length \: of \: the \: retangle \: = 8x \\ 8 \times 4 = 32cm$
