Tina is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 15 inches × 12 1/3 inch
erastova [34]

Answer:

Step-by-step explanation:

Remark

This is an "in theory" type of question. She's going to actually need a little more.

Area 1

L = 15

W = 12 1/3

Area = L*W

Area = 15 * 12 1/3                    I wonder if you know what the distributive property is. I'll try it. If you don't understand, leave a remark

Area = 15 * (12 + 1/3)              Multiply both parts by 15

Area = 15*12 + 1/3 * 15

Area = 180 + 5

Area =                                                                          185 square inches.

Area 2.

This is a little harder because their are

2 fractions.

The easy way to do this is change to decimals

L = 10 1/3 = 10.33333333

W = 10 1/4 = 10.25

Area = 10.3333333 * 10.25

Area =                                                                 <u>       105.92</u>      Add

Total Area

The total area =                                                        290.92
