Answer:
50cm²
Step-by-step explanation:
Let the width be x cm
The length will be x + 5 cm
Perimeter is 30cm
Perimeter is given by (2 × length) + ( 2 × width)
2(x + 5) + 2x = 30cm
2x + 10 + 2x = 30cm
4x = 20cm , x = 20/4 = 5cm
x (width) = 5cm
Length = 5 + 5 = 10cm
Area = Length × width
Area = 10cm × 5cm = 50cm²
