Question

A rectangle garden has a lenght which is longer than the width 30 cm. What is the area of that garden? Know that the perimeter of that garden is 65 cm.

Answer 1

The area is 75cm

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
