Question

I don’t understand if I have to maybe like divide or multiply or add or subtract

Answer 1

Divide

Explanation:

Area = length×width

But you know the Area, so you have to divide to find the missing dimension.

Area/width = height

OR

Area/height = width

Your question gives length, so

Area/length = width

16.02/4.5 = width

3.56 = width

Answer 2

3.56

Explanation:

Parameters given:

Area of the rectangular garden = 16.02m^2

Length of the rectangular garden = 4.5m

The Area of a rectangle can be calculated for using the formula below

Area (square meters) = length (meters) × width (meters)

Therefore, 16.02m^2 = 4.5m × width

Width = 16.02m^2 / 4.5m

Width = 3.56m

Therefore the width in meters of the garden is 3.56m
