Answer:
The area is 75cm
Step-by-step explanation:
Firstly, the perimeter is 65 cm and the width of the rectangle is 30 cm, so using this information we can figure out the length of the rectangular garden.
The formula for perimeter is L+L+W+W, you add all sides. The rectangle has 4 sides and 2 of those sides are 30 cm. 30+30= 60, so now we know what the width added up is. So we do this to find the length: 65-60=5, and then 5÷ 2 = 2.5. So now we use the formula for area: L × W: 30 × 2.5=75
