Which equation can be used to find A, the area of a square that has a perimeter of P units?
Responses
A A = P × 4A = P × 4
B A= (P + 4)A = ( P + 4)
C A = (P ÷ 4) × (P ÷ 4)A = ( P ÷ 4) × ( P ÷ 4)
D A= (P × 4) ÷ 4A = ( P × 4) ÷ 4

Given that the area of a trapezoid is `(1/2)*(sum of parallel sides)*height`, we can calculate the area of Becca's backyard trapezoid as follows:
Area = (1/2)(10 + 6) * 8
Area = (1/2)(16) * 8
Area = 8 * 8
Area = 64 square meters
Therefore, the correct response would be B. 60 m^2.
Area = (1/2)(10 + 6) * 8
Area = (1/2)(16) * 8
Area = 8 * 8
Area = 64 square meters
Therefore, the correct response would be B. 60 m^2.

We can find the area of an isosceles trapezoid using the formula for the area of a trapezoid: (1/2) * (sum of parallel sides) * height.
Given an isosceles trapezoid where the two parallel sides are 12 in and 18 in and the height is 5 in, the area would be:
Area = (1/2) * (12 + 18) * 5
Area = (1/2) * 30 * 5
Area = 0.5 * 30 * 5
Area = 15 * 5
Area = 75 square inches
Therefore, the correct response is not listed in the options but should be 75 in^2.
