Answer (bolded and underlined):

The area of Charlen's rhombus is 1/9 of the area of Jerry's rhombus

The base of Charlene's rhombus is 5 inches and the height is 3 inches, giving it an area of 15 square inches

Explanation:

One of the formulas we can use for area of a rhombus is given by,

A = bh, where

  • A is the area in square units,
  • b is the base,
  • and h is the height.

Area of Jerry's Rhombus: First, we can calculate the area of Jerry's rhombus by plugging in 15 for b and 9 for h in the area formula and simplifying:

A = 15 * 9

A = 135 in^2

Thus, the area of Jerry's rhombus is 135 in^2.

Area of Charlen's Rhombus: Before we're able to find the area of Charlene's rhombus, we'll need to find the base and height:

Base of Charlene's Rhombus: Since we're told that the base of Charlene's rhombus is 1/3 the base of Jerry's, we can find the base by multiplying 1/3 by 15 (base of Jerry's rhombus):

b = 1/3 * 15

b = 15/3

b = 5 in

Height of Charlen's Rhombus: Since we're told that the height of Charlene's rhombus is 1/3 the height of Jerry's, we can find the height by multiplying 1/3 by 9 (height of Jerry's rhombus):

h = 1/3 * 9

h = 9/3

h =3 in.

Now that we know the base and height of Charlen's rhombus, we can find the area of Charlen's rhombus by plugging in 5 for b and 3 for h in the area formula and simplifying:

A = 5 * 3

A = 15 in^2

Thus, the area of Charlene's rhombus is 15 in^2

Comparing the areas of Charlene and Jerry's rhombi:

  • We see that the area of Charlen's rhombus is 15 and the area of Jerry's rhombus is 135.
  • If we divide the two values, we get 135 / 15 = 9.
  • Thus, the area of Charlen's rhombus is 1/9 the area of Jerry's rhombus, which you can see by multiplying 1/9 by 135:

1/9 * 135 = 15
