Answer:
192 ft²
Step-by-step explanation:
Area of rectangular backyard = 1248 ft²
Width of backyard = 52 ft
Length = x
Area of rectangular backyard = Length * width
1248 = x * 52
x = 1248 / 52
x = 24 feets
Hence, x = height of triangular garden
Area of triangle = 1/2 base * height
Area = 1/2 * 16 * 24
Area = 192 ft²
