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.

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 ...
