Question

The length of a rectangle is 5 units more than the width. The area of the rectangle is 36 square units. What is the length, in units, of the rectangle?

Answer 1

The length of the rectangle is 9 units

Explanation:

1. Write down what we know:

• Area of rectangle = L x W
• L = W + 5
• Area = 36

2. Write down all the ways we can get 36 and the difference between the two numbers:

• 36 x 1 (35)
• 18 x 2 (16)
• 12 x 3 (9)
• 9 x 4 (5)
• 6 x 6 (0)

3. Find the right one:

• 9 x 4 = 36
• The difference between 9 and 4 is 5

Hence the answer is 9 units

Answer 2

The length is 9 units

Explanation:

Lenght is 9, width is 4,

9 x 4 = 36
