What are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.?
o A. P= 35 in., A = 300 in.2
O B. P = 70 in., A = 300 in.2
o C. P = 300 in., A = 70 in.2
o D. P = 35 in., A = 200 in.2

Answer:

B. P = 70 in; A = 300 in²

Explanation:

The perimeter is the sum of the side lengths. Opposite sides are the same length, so the perimeter is ...

P = 20 in + 15 in + 20 in + 15 in = 2(20 in +15 in) = 2(35 in)

P = 70 in.

Only answer choice B has the correct value. (Its area figure is also correct.)
