The constant of proportionality is 4. Also, look at 36, and 9 because you could have just divided it it is not as complicated as you think.
Hey mate
here is your answer
length and width are given in the ratio are ;(4:7)
area of rectangle = (l×b)
therefore,
4x×7x=700
28x^2=700
x^2=700/28
x^2=25
x=5
length =4x=4×5=20, lenght =20 and width =7x so, 7×5=35 width.....
