Question

The ratio of length to width (measured in inches) in a rectangle is 4∶7. find the length of the rectangle if the area is known to be 700 inଶ.

Answer 1

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.....
