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?
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
