Answer 2

Square has the greater area and by 137 cm².

Step-by-step explanation:

Given : Compare the areas of a square 15 cm on each side and a rectangle 11 cm by 8 cm.

To find : Which figure has the greater area and by how much ?

Solution :

A square 15 cm on each side.

The area of the square is $A=s^2$

$A_s=(15)^2$

$A_s=225\ cm^2$

A rectangle 11 cm by 8 cm.

The area of the rectangle is $A=l\times b$

$A_r=11\times 8$

$A_r=88\ cm^2$

The area of square is greater than the area of rectangle by

$A=A_s-A_r$

$A=225-88$

$A=137\ cm^2$

Therefore, square has the greater area and by 137 cm².
