Step-by-step explanation:
The area (A) of the whole sign is calculated as
A = bh ( b is the base and h the height )
Here b = 40 and h = 35, thus
A = 0.5 × 40 × 35 = 20 × 35 = 700 cm²
The area of the inner triangle is calculate as
A = 0.5 × 32 × 28 = 16 × 28 = 448 cm²
The area of the border is the difference between the whole sign and the inner triangle, that is
area of border = 700 - 44 8 = 252 cm²
