Step-by-step explanation:
Area of rectangle
l × b
12 × 6
= 72
area of actual figure
72-2×2
=68ft.
I need the model and the rest of the question to help you ;-;
Pythagoras theorem:
hypotenuse²=leg₁²+leg₂²
Data:
leg₁=8
leg₂=15
hypotenuse=s
hypotenuse²=(8)²+(15)²
hypotenuse²=64+225
hypotenuse²=289
hypotenuse=√289
hypotenuse=17
Answer: s=17
Equal sets have the exact same elements, so they must have the same number of elements. Therefore, equal sets must also be equivalent. No, not all equivalent sets are also equal sets
