Question

Stanley bought a rectangular piece of land to build an amusement park. The entire area of his land is 720 km2. The length of the land is 5 times the width of the land. What is the length and width of the piece of land that Stanley bought to build his amusement park?

Answer 1

Width=12 km

Length=60 km

Explanation:

Area of rectangle = length x width

Length=5 x width

so, x(5x)=720

5
`x^(2)`=720

`x^(2)`=144

x=sqrt(144)=12

Width=12 km

Length=60 km
