What are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.?
A. P = 35 in., A = 300 in.2
B. P = 70 in., A = 300 in.2
C. P = 300 in., A = 70 in.2
D. P = 35 in., A = 200 in.2
The formula for the perimeter of a rectangle is P = 2l + 2w, where l is the length and w is the width. The formula for the area of a rectangle is A = lw.
Plugging in the values given, we get:
P = 2(20) + 2(15) = 70 in.
A = 20 x 15 = 300 in.2
Therefore, the correct answer is B. P = 70 in., A = 300 in.2.
