find the missing dimensions on the figure

Answer 1

Answer:

r = 2 and n = 3

Step-by-step explanation:

9 = r + 3+ 4

9 = r + 7

r = 2

10 = n +2 + 5

10 = n + 7

n = 3

Answer 2

Answer:

r = 2 ft

n = 3 ft

area = 61 ft²

explanation:

• total length : 10 ft

• total width : 9 ft

-------------------------------

• n + 2 + 5 = 10

• n = 10 - 7

• n = 3 ft

-------------------------------

• r + 3 + 4 = 9

• r = 9 - 7

• r = 2 ft

-----------------------------

Area of the entire figure:

• length * width

• 9 ft * 10 ft

• 90 ft²

Area of the missing side:

• 5 * (3+2) + 2 * 2

• 29 ft²

So area of the shape:

• 90 ft² - 29 ft²

• 61 ft²
