Abbey Howard · Answer 1

14cm²

Step-by-step explanation:

Area of a triangle (A) is 1/2bh where;

b is the base of the triangle

h is the height of the triangle

Given the base = 7cm and height = 4cm,

Substituting the given values into the formula of area of a triangle we have;

A = 1/2*7*4

A = 14cm²

Therefore the area of the triangle is 14cm²
