STEP 1
We use the formula for the area of a triangle to solve the question.
Area = 1/2 x base x height
where base = 2.7cm
STEP 2
Substituting the appropriate values in the formula
10.26 = 0.5 x 2.7 x height
10.26 = 1.35h
divide both side by 1.35
Height = 7.6 cm
STEP 3
We convert the value of the height to feet
1cm = 0.0328084 ft
therefore, 7.6 cm would give 0.249344ft
STEP 4
We round to the nearest hundredth
Height = 0.25ft
Blank 1 = 0.25
Blank 2 = ft
