Finding the perimeter? the length of a rectangle is 5cm longer than its width. if the perimeter of a rectangle is 30cm find it’s area

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

yeah and the opposite of cheating is studying ( you should try it some time)
