Rectangles and squares.
heh
Largest area = pi*182 = 1017.876 square cm to 3 dp
For a square Area = Side2 thus Side = √Area = √81 = 9cmFor a square, Perimeter = 4 x Side = 4 x 9 = 36cm
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
The area of square is : 36.0
You have to cut the trapezoid into three shapes. The three shapes will be two triangles and one rectangle or square. You have to find the area of these three shapes and then add all of the three areas up to find the area of the trapezoid.
36cm
well, area is length times width. If all the side lengths are 36cm and formula is length times width. Then its 36 times 36 which equals 1296
Largest area = pi*182 = 1017.876 square cm to 3 dp
Since the lengths on both sides of the square are the same the side length will be 6cm.
For a square Area = Side2 thus Side = √Area = √81 = 9cmFor a square, Perimeter = 4 x Side = 4 x 9 = 36cm
One side equal to 6cm perimetre is 6*4=24cm
144.we should plus into 36+36+36+36=144.
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
Multiply the width by the length. e.g. you have a square that is 6 by 6 cm. 6x6 is 36, so the answer is 36cm squared.
Perimeter is 24cm
The perimeter is 24cm ******************************** First divide the perimeter by 4, then times the answer by 2, to get the area. Thus: (36 / 4 = 9) x 2 = 18 cm2
The area of square is : 36.0
