Answer 1

Heather's model is 324 square feet and Ellie's is 300 square feet. Therefore Heathers models is 24 square feet more than Ellie's model.

Answer 2

Answer:

Heather's model has greater area by 24 sq.ft.

Step-by-step explanation:

Given : Ellie's model represented 20 feet by 15 feet.

           Heather's model represented 18 feet by 18 feet.

To Find: Whose floor model represents the greater area? How much greater?

Solution:

Length of Ellie's model = 20 feet

Width of Ellie's model = 15 feet

Area = $Length \times Breadth$

       = $20\times15$

       = $300ft^2$

Length of Heather's model = 18 feet

Width of Heather's model = 18 feet

Area = $Length \times Breadth$

       = $18\times18$

       = $324ft^2$

Thus Heather's model has greater area by (324-300)= 24 sq.ft.
