Answer:
4 metres
Step-by-step explanation:
The garden is in the form of a rectangle. The area of a rectangle is denoted by A = lw, where l is the length and w is the width.
Here, we're given the length is l = 7 and the area is A = 28, so we can plug these into the formula:
A = lw
28 = 7 * w
Divide both sides by 7:
w = 28 / 7 = 4
Thus, the width is 4 metres.
