Answer:
13.4 left
Step-by-step explanation:
From the diagram we have
Base =

Height =

Area = Base × Height
126 =

⇒ Expand the double bracket
126 =

⇒ Subtract 126 both sides
0 =

⇒ Factorise the quadratic expression
0 =

⇒ Equating each factor to zero


We need the positive value of

so we use

Height = 5+1 = 6
Base = 4(5)+1 = 21
