Question

the length of a rectangle is 40cm while its ratio is 12:1 in its area and length to find the length and width of the rectangle

Answer 1

given length=40cm and the ratio of area to length=12:1

therefore area would be 40×12=480

we know that area of rectangle is = length×breadth

thus putting value we get

40×b=480

therefore b=480/40= 12cm
