Answer:
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
This is an isosceles triangle. The angles in the legs are congruent therefore making the legs congruent as well. Hope this helps!
