The area of the trapezoid is 20 in².
Solution:
Given data:
Length of the bottom base = 7 in
Length of the top base = 3 in
Height of the trapezoid = 4 in
Step 1: Area of the trapezoid formula,
Step 2: Substitute the given values in the formula.
Step 3: Add 7 and 3.
Step 4: Divide 10 by 2, we get
Step 5: Multiply 5 by 4, we get
A = 20 in²
The area given in the picture is wrong.
The area of the trapezoid is 20 in².
Answer:
or
Step-by-step explanation:
The expression can be simplified by first writing the fraction under one single radical instead of two.
5/15 simplifies because both share the same factor 5.
It becomes
This can simplify further by breaking apart the radical.
A radical cannot be left in the denominator, so rationalize it by multiplying by √3 to numerator and denominator.
