1. D) p=9.4 m; A= 4.8 m^2
2. C) 189 ft^2
1. Find the perimeter and area of a rectangle with a length of 3.2 m and a width of 1.5 m.
The perimeter of a rectangle is simply twice the sum of it's length and width, so
2(3.2m + 1.5 m) = 2*4.7 = 9.4 m
The area of a rectangle is the product of its length and width, so
3.2 m * 1.5 m = 4.8 m^2
Of the available choices, D matches with p=9.4 m; A= 4.8 m^2
2. Find the area of a triangle with a base of 27 feet and a height of 14 feet.
The area of a triangle is 1/2 base times height, so
0.5 * 27 ft * 14 ft = 189 ft^2
Of the available choices, C matches with 189 ft^2
