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.)
I’m pretty sure it’s 2:5 hope that helps!
Please elaborate on this so that I can help you.
Step-by-step explanation:
x=−y−2z+3
x=y+32z+1
x=13y+23z+13
