By Pythagoreans' theorem,
7.5² = l² × b²
56.25 = l² × b²
Since l = b
56.25 ÷ 2
= l²/b²
= 28.125 mm
∴ l = √28.125
= 5.3033 mm
Area of square
= √28.125 × √28.125
= 28.125 mm²
≈ 28.1 mm² (3s.f.)
Add 12 to both sides of the equal sign, then simplify.
1/6 is larger. Say you have a pizza, if you had 7 pieces of pizza, they would be smaller than 6 slices of pizza.
