Question

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 divided One-half (4) (3.5) by 5. She should have divided One-half (4) (3.5) by 5 squared. She should have multiplied (4) (3.5) by 5. She should have multiplied One-half (4) (3.5) by 5 squared.

Answer 1

Answer: She should have multiplied One-half (4) (3.5) by 5 squared.

Step-by-step explanation:

The calculation of Beth is wrong. Since Beth enlarged the triangle below by a scale of 5, she should find the area of the traingle and then multiply by 5².

This will be:

= 1/2 × 4 × 3.5 × 5²

= 2 × 3.5 × 25

= 175cm²
