whats are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.?
The perimeter of a rectangle can be calculated using the formula P = 2(l + w), where l is the length and w is the width.
P = 2(20 + 15) = 2(35) = 70 inches
The area of a rectangle can be calculated using the formula A = l × w.
A = 20 × 15 = 300 square inches
So, the perimeter is 70 inches and the area is 300 square inches.
