Answer:
9.53cm*2
Step-by-step explanation:
The correct answer is calculate half the isosceles length to get the height.
= 4.24/2 = 2.12^2 = a (smallest) x b^2 = (3^2 =(c^2))
= 2,12^2 = 4.4944 xb^2 = 9
9- 4.4944 = 4.49
Area 1/2 base x height
= 2.12 x 4.4944 = 9.528128
If cm then we would round up 3sf to 2sf only and say 9.53cm^2
