area of a square is s^2, where s is the length of any side
so the area is equal to 3.5cm times 3.5cm
which is 12.25 cm^2
D

The area of a rectangle equals the length multiplied by the width (A= L x W). A square is a type of rectangle. In a square, the sides are all equal. Therefore, if any of the sides of a square is 3.5 cm, all of the sides are 3.5 cm. The length and width both equal 3.5 cm, therefore 3.5 cm X 3.5 cm equals the area of the square, which is 12.25. Area is always represented in cm^2, so the answer is d) 12.25 cm^2.
God bless.

a million)If the fringe is 36 inches, then, divided by utilising 4, the facets may be 9 inches each. Now, to discover the section, you basically sq. the facets: 9² = eighty one the section is eighty one inches² ======================== 2)For the rectangle, you will observe it has 2 instruments of equivalent facets. permit x be the width of the rectangle you're searching for: x + x + 7 + 7 = 35 2x + 14 = 35 2x = 21 x = 10.5 The width is 10.5cm ======================== 3)permit the facets of the sq. be x (all facets of a sq. is equivalent). utilising Pythagoras (notice that the diagonal creates a marvelous-angled triangle): x² + x² = 7² 2x² = 40 9 x² = 24.5 x = ?24.5 So the facets are ?24.5 ft each. To get the section, sq. the facets: (?24.5)² The squareroot and the ² cancel out, leaving 24.5 Your section is 24.5 ft²

The area is 12.25 cm2
A square has 4 equal sides, "so any of its sides" is the same as "all 4 sides"
The area of a square is (any side ) squared
so, 3.5 squared is 12.25
HOPE THIS HELPS

area = length * width
in a square, length = width = side so area = side * side = side^2
this is why we say side "squared"
(3.5 cm)^2 = 12.25 square cm.
