Question

a rectangle has a length to width ratio of 4:3 if its length is 20 cm what is its width

Answer 1

Answer:

15cm is the breadth of the rectangle

Answer 2

Answer:

the ratio is 4:3

so take 4/3=20/x where x is the width

taking x on right side and 3on left side we get 4x=20×3

then bringing 4 to right side we get

x=20×3/4

so x=5×3

x=15

therefore the width is 15 cm
