Math Review
Question: 10
Page: 260
Difficulty: medium


GIVEN: AB = 5, AF = 7, and FD = 3
Add the information to the diagram
Image


(a) Area of ABCD
Area of rectangle = (base)(height) = (10)(5) = 50


(b) Area of triangle AEF
Image
Area of triangle = (base)(height)/2
= (7)(5)/2 = 17.5


(c) Length of BD
Image
Since ∆ABD is a RIGHT triangle, we can apply the Pythagorean Theorem.
We get: 5² + 10² = (side BD)²
Simplify: 25 + 100 = (side BD)²
Simplify: 125 = (side BD)²
Solve: side BD = √125 = √25 x √5 = 5√5


(d) Perimeter of ABCD
Add lengths of 4 sides
Perimeter = 5 + 10 + 5 + 10 = 30

Cheers,
Brent
