Answer:
Therefore, the perimeter and area of the given shapes are:
a. Perimeter = 47m, Area = 133m²
b. Perimeter = 58cm, Area = 210.25cm²
c. Perimeter = 83.6cm, Area = 420cm²
Step by step solved:
a. To find the perimeter of a rectangle with length L=14m and breadth B=9.5m, we use the formula:
Perimeter = 2(L+B)
Plugging in the values, we get:
Perimeter = 2(14m + 9.5m) = 2(23.5m) = 47m
To find the area of the rectangle, we use the formula:
Area = L x B
Plugging in the values, we get:
Area = 14m x 9.5m = 133m²
b. To find the perimeter of a square with side length=14.5cm, we use the formula:
Perimeter = 4 x side
Plugging in the value, we get:
Perimeter = 4 x 14.5cm = 58cm
To find the area of the square, we use the formula:
Area = side²
Plugging in the value, we get:
Area = 14.5cm x 14.5cm = 210.25cm²
c. To find the perimeter of a rectangle with length L=25cm and breadth B=16.8cm, we use the formula:
Perimeter = 2(L+B)
Plugging in the values, we get:
Perimeter = 2(25cm + 16.8cm) = 2(41.8cm) = 83.6cm
To find the area of the rectangle, we use the formula:
Area = L x B
Plugging in the values, we get:
Area = 25cm x 16.8cm = 420cm²
