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

Answer:
x² - 5x = 14
x = -2 or x = 7
Step-by-step explanation:
x² - 5x = 14
x² - 5x - 14 = 0
(x+2)(x-7) = 0
x = -2 or x = 7
The triangle must be isosceles, due to the perpendicular bisector. Therefore, the expression 20 - 15 can be used to yield an answer of B. 5.
Hope this helps!
