x = 3 and y = 5
Solutions,
2x – y – 4 = 0
2×3 – y – 4 = 0
6 – y – 4 = 0
–y = –2
y = 2
2x – y – 4 = 0
2×5 – y – 4 = 0
10 – y – 4 = 0
–y = –6
y = 6

ABCD is a square
Area of square = (side)²
A = 2 × 2
A = 4 cm²

Area of triangle = 1/2 × b × h
A = 1/2 × 2 × 4
A = 4 cm²

Area of quadrilateral = Sum of area of square and triangle .
A = 4 cm² + 4 cm²
A = 8 cm²
