Answer:

B.

Explanation:

We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5.

We are asked to find the area of the enlarged trapezoid. The area of the original trapezoid is 36 square inches.

Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.

The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.

Therefore, the area of the enlarged trapezoid would be and option B is the correct choice.

Answer:

New area by scale of 1.5 = 81 in²

Explanation:

Given:

Current area = 36 in²

Find:

New area by scale of 1.5

Computation:

New area by scale of 1.5 = Current area x (scale factor)²

New area by scale of 1.5 = 36 x (1.5)²

New area by scale of 1.5 = 36 x (2.25)

New area by scale of 1.5 = 81 in²
