Question

which figure has a greater area? 12.1 cm 18.7 cm 13.9 cm 13.9 cm

Explanation:

Step1: Calculate area of rectangle

The area formula for a rectangle is $A = l\times w$. For the rectangle with length $l = 18.7$ cm and width $w=12.1$ cm, we have $A_{1}=18.7\times12.1 = 226.27$ $cm^{2}$.

Step2: Calculate area of square

The area formula for a square is $A = s^{2}$. For the square with side - length $s = 13.9$ cm, we have $A_{2}=13.9\times13.9=193.21$ $cm^{2}$.

Step3: Compare areas

Since $226.27>193.21$, the rectangle has a greater area.

Answer:

The rectangle has a greater area.
