Given that,
The area of a certain number of triangles is equal to the exponents of the prime factors of the number 1628 and each prime factor represents a triangle.
Prime factors of 1628 are:
1628=22×3×7×19.
Since there are 5 prime factors,
⇒ The number of given triangles are = 5
The area of the triangles is the sum of powers of the prime factors.
⇒The sum of areas of the triangle = 2 + 1 + 1 + 1
= 5 square units
The number of triangles is 5 and the sum of areas of the triangle is 5 square units.
