Beth enlarged the triangle below by a scale of 5. A triangle with a base of 4 centimeters and height of 3.5 centimeters.

She found the area of the enlarged triangle. Her work is shown below.

One-half (4) (3.5) (5) = 35 centimeters squared

What was Beth’s error?

She should have multiply each of the sides the scale value before multiplying to find the area.

Step-by-step explanation:

They are two sides to the triangle which is the base and the height  and each side have a different length so you will have to first multiply each side length by the scale value to find the new length of the enlarged triangle.

base:  4 *5 = 20

height :  3.5 * 5 = 17.5

Now since the base is 20 cm and the height is 17.5 cm you will use the area of a triangle formula to solve for the area.

A = 1/2* b * h

A = 1/2 * 20 * 17.5

A =  10* 17.5

A = 175  

or she could have multiply 35 which is the number he obtained by another 5 to find the area.

1. 34

2. 268

3. x=14.4
