Answer:
2.5 ft.
Step-by-step explanation:
The area of the side of each smaller square = 100 / 16 sq ft.
= 6.25 sq feet.
So the length of each smaller square = square root of 6.25
= 2.5 ft.
Answer:
A
Step-by-step explanation:
The rectangle has an area of 30ft^2
Each triangle has an area of 25ft^2
25+25+30=80
An obtuse triangle must have an angle greater than 90degrees (cannot equal 90). Therefore, A. would be the correct answer. This is because A. is the only set of angles that includes an angle greater than 90. Also, all angle measures add up to equal 180degrees.
