Question

1. a glass company is to make a panel of glass for a front door. what is the area of the glass panel if it is 120 cm long and 20 cm wide?

Explanation:

Step1: Identify the shape and formula

The glass panel is rectangular. The area formula for a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width.

Step2: Substitute the values

Given $l = 120$ cm and $w = 20$ cm. So $A=120\times20$.

Step3: Calculate the result

$120\times20 = 2400$ $cm^{2}$.

Answer:

$2400$ $cm^{2}$
