Answer: d = 147/4 or 36.75
Edward didn't isolate for 'd' by rearranging the terms.
(4/7)d = 21 (Multiply both sides by 7 to get rid of the 7 on the left side)
4d = 21 · 7
4d = 147 (Divide both sides by 4 to isolate for d)
d = 147/4 or 36.75
Answer: ≈ 21.46 m²
Step-by-step explanation:
Area of square = 10 x 10 = 100 m²
Area of circle = π(5²) = 25π m²
Area of total = 100 - 25π = 21.46018366
≈ 21.46 m²
