Answer:

b) dilation

Dilation:

FIgure has different size.

The area of a parallelogram is 91.2cm2, base is l2cm. Find its height.​
bulgar [2K]

Answer:

7.6 cm

Step-by-step explanation:

Area = 91.2 cm²

Base = 12 cm

Height =?

To find the height, let the height be h.

<u>Let us solve it now.</u>
