Answer:
l = 7m, w = 4m
Step-by-step explanation:
Let w be the width
l be the length
Given:
w = l -3
A = 28 sq m
Formula:
Area = length x width
A = lw
Substitute the given to the formula
A = lw
Since we're talking about dimensions, consider only the positive answer. l = 7m
Substitute
the value of l to w = l-3
w = 7-3
w = 4m
