Question

A trapezoid ABCD is formed by adding the isosceles right triangle BCE with base 5 inches to the rectanqh ABED where DE Is t Inches. What Is the area of the trapezoid In square Inches? Pick one of the choices

Answer 1

Solution:-
The area of trapezoid ABCD = The area of rectangle ABED, which is t × 5 (Since BE = EC = 5 inches) + the area of triangle BEC, which is (5 × 5)/2. 
So, Area of trapezoid = 5t + 25/2
⇒ (5t + 12.5) square inches.
