a) In rectangle,
l = 2y ‐ 4
b = x + 3
l = b + 8 ( Given in ques.)
2y - 4 = x + 3 + 8
2y = x + 11 + 4
x = 2y - 15 — (i)
b) In Triangle,
2x + 4y + 6 = 56 (Sum of all sides = Perimeter)
2x + 4y = 50
2(2y – 15) + 4y = 50 ( From (i) )
4y – 30 + 4y = 50
8y = 80 cm
y = 10 cm.
c) Substituting the value of y in (i),
x = 2y – 15
x = 2(10) – 15
x = 20 – 15
x = 5 cm...
