How long is the perimeter of a square with an area of 25cm squared?
P = 20cm
How many tiles of 10cm by 20cm fit in 1m squared area?
50
If a rectangles area is 12 cm squared what is the perimeter?
12
How could you do the area of a square?
multiply the width by the length, e.g. 5cm= width, 4cm= length, 5x4= 20, 20cm squared
How do you find an area of an unusual shape?
You divide the shape into smaller shapes you can calculate, like rectangles and triangles. If the shape is irregular, you have to approximate, for example by dividing it into many narrow rectangles. This technique is called "integration".
What is the surface area of a Lego man?

How do you add area of a semicircle and area of a rectangle?
Simply add the numbers up For example, If the area of a semicirce is 20cm squared and the area of a rectange is 25cm squared, then the total area would be 20 + 25 = 45

Find 4 rectangles with same area with different perimeter?
10cm by 10cm (perimeter=40cm), 5cm by 20cm (perimeter=50cm), 50cm by 2cm (perimeter=104cm), 100cm by 1cm (perimeter=202cm). All of these rectangles' areas are 100cm2
What is the area of a 20 cm cercle to the nearest cm-squared?
If 20cm is the diameter then radius is 10cm and area = Pi * r2 = Pi * 100 = 314 to the nearest square centimetre.
How do you work out the area of an L shape?
You should break it down in to smaller shapes. Two rectangles. Then figure out all the lengths. Multiply to find the area of the two rectangles. then add the products to get the final area.
