What is the area and perimeter for these two shapes?

Answers

A:
Area: 289 m
Perimeter: 51 m

B:
Area: 4 m
Perimeter: 8 m

Answer:

Shape 1:

Area = l × w

17 m × 17 m

Area = 289 meters

Perimeter = P = 2 (l + w)

2 · (17 + 17)

Perimeter = 68 meters

Shape 2:

Area = l × w

2 × 2

Area = 4 feet

Perimeter = P = 2 (l + w)

2 · (2 + 2)

Perimeter = 8 feet

C. that turns through 10/360 of a circle has a measure of 36°
D. angle that turns through 1/12 of a circle has a measure of 1°​

The answer is B
An angle that turns throughly 10/360 of a circle has a measure of 10 degrees
