. 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?

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.

Step-by-step explanation:

b

She forgot to square the scale factor.

Step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
