Alright so let's make Jan's age "J" and Trits' age "T"
Jan's age is 3 years less than twice trits age: 2T-3=J
The sum of their ages is 30: J+T=30
We can plug the first equation into the second:
2T-3+T=30
3T-3=30
3T=33
T=11   So Trits' age is 11, and we can plug 11 for T for either equation
2(11)-3=J
19=J
Jan is 19 and Trit is 11 :)

Answer:

28 units²

Step-by-step explanation:

→ Work out the size of the triangle if it was a full rectangle

Height = 4 and Base = 2

→ Work out area of triangle

0.5 × Height × Base ⇒ 0.5 × 4 × 2 ⇒ 2 × 2 ⇒ 4

→ Minus the area of the triangle from the "imaginary full' rectangle

Area of rectangle = Length × Width ⇒ 8 × 4 ⇒ 32

32 - 4 = 28
