Oh, dude, a shape with an area of 36cm square could be a square with sides of 6cm each, a rectangle with dimensions 4cm by 9cm, or even a circle with a radius of about 3.8cm. Like, there are a bunch of shapes that could fit the bill, so it's not just one specific shape, ya know?

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.
