A rectangle garden with an area of 960 m2 in a school which measures 1 km by 800 m. Find the area besides the garden.
i need to know what it is
You are given the area of the garden (960 m^{2}) and the dimensions of the school that the garden is in (1 km by 800 m).
To find the total area excluding the garden, we first need to calculate the area of the school that the garden is in. Once we have that, subtracting the area of the garden from the total area of the school gives us the area without the garden.
Area of school = (1 km) · (800 m)
==> Before we go any further, the units of the dimensions have to be the same. Convert the measurement given in kilometers (km) into meters (m). Since there are 1000 meters in 1 kilometer, multiply 1 km by 1000m/1km:
(1 km)·(1000 m/1 km) = (1 km·1000 m)/(1 km) = 1000 m
Area of school = (1 km)·(800 m)
= (1000 m)·(800 m)
= 800,000 m^{2}
Total area excluding the garden = Area of school - Area of garden
= 800,000 m^{2} - 960 m^{2}
= 799,040 m^{2}
