NEED HELP ASAP I WILL GIVE BRAINLIEST
The triangle has been reduced by a scale of

. What is the area of the reduced triangle?

A large rectangle has a base of 30 centimeters and height of 25.5 centimeters. A smaller rectangle has a base of b and height of a.

Maria solved the area problem below. What was her error?

(12 ) (25.5)(30) (15 ) = 76.5cm²

Maria solved the area problem below. What was her error?

She found the perimeter.
She forgot to square the scale factor.
She forgot to multiply by One-half for the area of the triangle.
She should have divided by the square of the scale factor.

The correct option is;

She forgot to square the scale factor

Step-by-step explanation:

The parameters given are;

Dimensions of large rectangle;

Base = 30 cm

Height = 25.5

Dimensions of the small rectangle;

Base = b

Height = a

The formula to find the area of scaled dimension (small triangle) is given as follows;

Area of small triangle = (Scale factor)² × Original (or actual) area

Whereby the area, A, of a triangle is given as follows; The smaller triangle area, , should therefore be given as follows; Plugging in the values, we have; However, from the question, we have;

(1/2)(25.5)(30)(1/5) = 76.5 cm²

Therefore, the correct option is that she forgot to square the scale factor.

2. Answer: It’s the second option
