Question

ITS TIMED PLS QUICK A gardener would like to add to their existing garden to make more flowers available for the butterflies that visit the garden. Her current garden is 45 square feet. If she added another rectangular piece with vertices located at (−21, 7), (−23, 7), (−21, 12), and (−23, 12), what is the total area of the garden? FOR 20 POINTS

10 ft2
55 ft2
225 ft2
450 ft2

Answer 1

55ft2

Explanation:

Find the area of the added rectangle

-23 - -21 = 2ft

12-7 = 5ft

A=bh = 2ft x 5ft = 10ft^2

add old area and new area

45ft^2 + 10ft^2 = 55ft^2

Answer 2

55 ft2

Explanation:

Since the x values are -21 and -23, it shows that they are 2 points away from eachother. They y values are 7 and 12 so they are 5 points away from eachother. Multiply 2 x 5 = 10 which is the area of the new garden. Since the old garden is 45 square feet, add 10 + 45 to get 55 square feet total.
