h = 3 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the height )
Here A = 7
=
← expressed as an improper fraction
and b = 5
=
, thus
×
× h =
, that is
h =
Multiply both sides by 8 to clear the fractions
21h = 63 ( divide both sides by 21 )
h = 3
