The net shows an equilateral triangle with side length 24 cm.
The area of an equilateral triangle of side length s is ...
... A = (√3)/4·s²
Using the above side length, the area is
... A = (√3)/4·(24 cm)² = 144√3 cm² ≈ 249.4 cm²
Your best choice is the first one:
... A) 249.6 cm²
(a) y >_ 13
(b) x > 17.5
Explanations:
(a)
24.2 - y <_ 11.2
- y <_ 11.2 - 24.2
-y <_ -13
y >_ 13
(b)
- 12.5 + x > 5
x > 5 + 12.5
x > 17.5
(<_ means “less than or equal to” and >_ means “greater than or equal to”)
