A garden is 75 cm long and 82 cm wide. A 5 cm wide road is made all around the inside of the garden. Find the area of the road?
Answer: 1470 cm²
Explanation
To find the area of the road, we need to find the area of the garden and subtract the area of the inner garden (without the road).
Garden area = Length * Width
= 75 cm * 82 cm
= 6150 cm²
Inner garden dimensions:
Length = 75 cm - 2 * 5 cm = 65 cm
Width = 82 cm - 2 * 5 cm = 72 cm
Inner garden area = 65 cm * 72 cm
= 4680 cm²
Road area = Garden area - Inner garden area
= 6150 cm² - 4680 cm²
= 1470 cm²
