1.) Answer:  1.4 times 1.5 or 1 2/5 multiplied by 1 1/2

If you add up the total length and width, the length measures 1.5 units and the width measures 1.4 units.

Area= (L)(W) so the expression is (1.5)(1.4). If converted to fraction, it is 1 1/2 multiplied by 1 2/5.

2.) Answer: 2.1 or 2  1/10

(1.4)(1.5)= 2.1 which also equals 2 1/10

3.) Mark has a cardboard that is cut up into 4 pieces. The dimensions are as followed, 1 inch by 1inch ,  1 inch by 1 1/2 inches,  1 inch by 2/5 inch, and  1/2 inch by 2/5 inch. What is the area of the card board? Answer: 2  1/10 

(1)(1)+(1)(1.5)+(1)(2/5)+(1/2)(2/5) = 1+1.5+1.4+0.2=2.1

4.) 7 multiplied by 4 or (7)(4)

Each unit square represents 1 square unit. Area= 28 square units

The dimensions are 7 by 4 so (7)(4)

5.) Area= 28 square units

The dimensions is 7 by 4 which equals 28.

6.) Katie has a painting that is 7 ft long and 4 wide. What is the area?

Area= 28 square feet
