Question

question 18 (1 point)
what is the area and perimeter of this rectangle?
3 feet
a. area = 36 feet, perimeter = 30 feet
b. area = 30 square feet, perimeter = 36 feet
c. area = 36 square feet, perimeter = 30 feet
d. area = 36 square feet, perimeter = 15 feet
9 feet

Explanation:

Step1: Calculate the area

The formula for the area of a rectangle is \(A = l\times w\). Here \(l = 12\) feet and \(w = 3\) feet. So \(A=12\times3 = 36\) square feet.

Step2: Calculate the perimeter

The formula for the perimeter of a rectangle is \(P=2(l + w)\). Substitute \(l = 12\) feet and \(w = 3\) feet. Then \(P = 2(12 + 3)=2\times15 = 30\) feet.

Answer:

C. Area = 36 square feet, Perimeter = 30 feet
