Question

a rectangle has an area of 18 square centimeters. which of the following could be the rectangles length and width? (area = length × width) choose all answers that apply: a 1 cm and 18 cm b 2 cm and 9 cm c 3 cm and 6 cm d 4 cm and 5 cm

Explanation:

Step1: Recall area formula

The area of a rectangle is $A = l\times w$, where $l$ is length and $w$ is width. We need to check each option.

Step2: Check option A

For $l = 1$ cm and $w = 18$ cm, $A=1\times18 = 18$ square - cm.

Step3: Check option B

For $l = 2$ cm and $w = 9$ cm, $A = 2\times9=18$ square - cm.

Step4: Check option C

For $l = 3$ cm and $w = 6$ cm, $A=3\times6 = 18$ square - cm.

Step5: Check option D

For $l = 4$ cm and $w = 5$ cm, $A=4\times5 = 20$ square - cm.

Answer:

A. 1 cm and 18 cm
B. 2 cm and 9 cm
C. 3 cm and 6 cm
