1. A square with a side measuring 3 cm.
Area = s²
Area = 3²
Area = 9cm²
2. A rectangle with length 7 cm and width 5 cm.
Area = LW
Area = 7(5)
Area = 35cm²
3. If the area of a square is 1,225 m², find its perimeter.
Area = s²
1225 = s²
s = √1225
s = 35m
Perimeter = 4s
Perimeter = (4)35
Perimeter = 140m
4. If the area of a rectangle is 152 cm² and its length is 19 cm, find the
width of the rectangle.
Area = LW
152 = 19w
w = 152/19
w = 8cm
5. If the circumference of a circle is 37.68 units, find its area.
C = 2πr
37.68 = 2(3.14)r
37.68 = 6.28r
r = 37.68/6.28
r = 6 units
Area = πr²
Area = 3.14(6²)
Area = 3.14(36)
Area = 113.04 square units
