Area = length x width. In a square these are the same so it is the square of a side, in this case the square of 9...
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm
Area = (length of a side)2 = 81 square centimeters Perimeter = 4 x (length of a side) = 36 cm.
9cm
18 square cm
Letting x be the length of the rectangle and (x - 8) be the width of the rectangle,x(x - 8) = 153,subtracting 153 from each side, x2 - 8x - 153 = 0,solving for x, (x - 17)(x + 9) = 0, then x = 17 or x = -9,substituting 17 for x, the dimensions of the rectangle are 17cm and 9cm.
Area is length times width. So... 9x9=81
7cm x 9cm= 63 sq.cms
Area for square is Base X Height. Since the length is all equal FOR a square The base and height is both 9cm So the answer is 81cm
The area of a rectangle is calculated by multiplying the length by the width. In this case, the area would be 18 square centimeters.
ok if the perimeter is 36cm and it is a square then you know all four sides are equal 36cm / 4sides = 9cm for each side A = L * W ( both the length and width are 9cm because each side is equal ) A = 9cm * 9cm A = 81cm2
63 X 9 X 7 = 3967 square cm.
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm
It is: 42+42+54+54+63+63 = 318 square cm
Area = (length of a side)2 = 81 square centimeters Perimeter = 4 x (length of a side) = 36 cm.
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
Area of the rectangle is 144cm. The sides of a square with the same ares is 12cm.
To find the area (A) of any rectangle, we multiply the length (l) by the width (w). In the case of a rectangle that is 11 cm by 9 cm, we do this:Arectangle = l x w = 11 cm x 9 cm = 99 cm2or 99 square centimeters.
