And artificial lake is in the shape of a rectangle and has an area of 9/20 square mi.² the width of the lake is 1/5 the length of the lake what are the dimensions of the lake

The dimensions of lake are length 1.5 miles and width 0.3 miles

Solution:

Given that,

Artificial lake is in the shape of a rectangle

Let the length of lake be "a"

The width of the lake is 1/5 the length of the lake

The area of lake is 9/20 square miles

The area of rectangle is given by formula:

Substituting the values we get,

Thus, we get

Thus the dimensions of lake are length 1.5 miles and width 0.3 miles
