The ratio of the area of a square of side 15 cm to that of a rectangle, 24 cm long, is 5 : 4 . What is the breadth of the rectangle

Answer 1

The breadth of the rectangle would be
`7.5\:cm`

Explanation:

Write down the ratio and then solve for unknown.

`(5)/(4)=(15\cdot 15)/(24\cdot w)\\\\5\cdot \:8w=4\cdot \:75\\\\w=(15)/(2)\\\\w=7.5\:cm`

Best Regards!

Answer 2

7.5cm

Explanation:

15²=225cm²

225/5=45

45*4=180cm²

180/24=7.5

7.5cm should be your answer. If not, I am sorry.
