**Part A: **5,333 square yards

**EX:** The length of the football field is 100 yards. The width of the field is **53** yards.

**Part B: **1/10 inch per yard

**EX:** The scale used in the drawing is 1 inch to 10 yards. I can represent this ratio in several different ways: 1 inch to 10 yards, 1 inch : 10 yards, **1 in/ 10 yd or 1/10**

**Part C: **10 inches

**EX: ** Set up a proportion where the numerators are the measurements in the scale drawing and the denominators are the actual measurements of the football field:

**1 in. / 10 yd. = × in. / 100 yd.**

**Cross multiply, and then divide both sides by 10 to solve for x:**

**100 = 10x**

**10 = x**

**Part D: **5 1/3

**EX:** Use the actual width of **53** yards and the scale to find the width of the field in the scale drawing.

Set up a proportion where the numerators are the measurements in the scale drawing and the denominators are the actual measurements of the football field:

**1 in / 10 yd = 53** **yd**

**Cross multiply, and then divide both sides by 10 to solve for x:**

**10x = 53**

**x = 160/3 ÷ 10**

**x = 16/3**

**x = 5**

**Part E: **53** **1/3

**EX:** In the scale drawing, the length of the football field is 10 inches and the width is **5** **inches. The area of a rectangle is length × width:**

area = length × width

**= 10 in. x 5** **in.**

**= 53** **sq. in. ( square inches)**

**Part F: **The ratio is 1 square inch to 100 square yards

**EX:** The area of the football field in the scale drawing is **53** square inches.

The area of the actual football field is **5,333** square yards.

The calculation for the ratio of the scaled area to the actual area is

**53** **sq. in. / 5,333** **sq. yd. = 1 sq. in. / 100 sq. yd.**
