Answer:
The area is 90 sq. cm
Step-by-step explanation:
Given
The variation can be represented as:
Area = 60, when l = 4 and w = 3
Required
Find Area, when l = 6 and w = 3
Represent the variation as an equation
Where k is the constant of variation.
Substitute 60 for A, 4 for l and 3 for w
Make k the subject
To get the value of Area when l = 6 and w = 3.
Substitute 5 for k, 6 for l and 3 for w in
<em>The area is 90 sq. cm</em>
