A garden is currently 4 meters wide and 7 meters long. If the area of the garden is to be doubled by increasing the width and length by the same number of meters, find the new dimensions of the garden, rounded to the nearest tenth.

Given,

Width (w) = 4 meters

Length (L) = 7 meters

So, area is 4*7 = 28 Meters sq

Area of garden is to be doubled so area is 2 * 28 = 56 Sq meters

And For that length and width should increase by same number so let it be x

so,

(4+x) * (7+x) = 56

By solving that u get,

X is approximately equals to 2.13,

so we can say it as 2.
